content: Just posted this on twitter, reposting here.My predictions for Robo-Cabs / Robo-TaxiPREDICTION #1:Robocabs that can match a human driver in practicality are *many* years away. Perhaps even a decade or more.Anyone talking next year is kidding themselves.And they could still suck in many situations.PREDICTION #2:People taking Robo-cabs won't like or trust traditional looking cars with an empty front seat and steering wheel whizzing around.Expect something different to win out.PREDICTION #3:Johnny Cab won't happen. People will detest humanoid robots trying to interact with them.PREDICTION #4:The "one bad experience" problem may seriously hamper initial Robo-Cab adoption.And with social media how it is, all you'll hear about are the bad experiences.The media & your Facebook friends will lap it up.Although, Facebook could be dead by then...

content: Quote from: EEVblog on May 15, 2019, 06:49:19 amThey don't have to. They have to be safer than human drivers, but in other respects it will be a question of price vs convenience. If a robocab is more convenient than the bus and cheaper than a normal cab (and possibly cheaper than the bus!) people will use them.Quote from: EEVblog on May 15, 2019, 06:49:19 amYes. Although last year Waymo said they would launch Waymo One without safety drivers in Phoenix this year. So far they have launched Waymo One but they are still using safety drivers. It's hard to tell how close they are to the goal because it's such a competitive market now that everything is kept secret.But Phoenix is only their first pilot project. It will take a few more years before they launch in other cities, and then a few more years before they start to expand the operating area. It will take decades before they will be operating outside the US I suspect.Quote from: EEVblog on May 15, 2019, 06:49:19 amThere will be many instances when the robocabs will seem stupid (because they are, it'snota general AI), especially in the beginning. But as long as it isn't safety related and doesn't cause too much inconvenience I don't think it will be a show stopper. People will use them as long as it is safe, cost effective and "good enough".Quote from: EEVblog on May 15, 2019, 06:49:19 amI think something different will win out but mostly for other reasons. You want to use all seats for passengers, and the operating companies probably doesn't want the passengers to try and interfere with the driving controls. So the steering wheel, etc, will be removed (or at least hidden).There will probably also be more specialised vehicles. You use a phone app to order a vehicle, so I assume you will fill in how many you are, where you are going and if you have any luggage or special needs, and then they send an appropriate car to handle your specific request.If a lot of trips are short with only one passenger for example, then there will probably be small 1-2 seated cars that can handle such requests. One can also imagine there will be mini busses that pick up people during rush hours for example. Time will tell.Quote from: EEVblog on May 15, 2019, 06:49:19 amAgree. A stupid animatronic puppet that annoys you and takes up precious space. Remember Clippy? People doesn't wan't a "human" interface in between them and the machine.Quote from: EEVblog on May 15, 2019, 06:49:19 amYes, if they rush it and launch big before the service is ready it will probably set them back many years because of the publicity backlash. But they have already invested so much in this, they won't abandon this idea easily.

content: I would argue that real autonomous driving (in a real world traffic situation you could encounter today in a car) could only work reliably withrealartificial intelligence (and not some brainless neuronal network giving somewhat nondeterministic results) so it could react to unexpected situations at least as good as a human driver.So even ten years from now sounds pretty much optimistic unless there is some unexpected breakthrough in AI. While I would really look forward to have autonomous driving in twenty years or so when I'm retired and half-blind, I would not entrust a car with my life that will decapitate me when mixing up a traffic sign with a truck.It's somewhat shocking to see how easily today's image recognition systems can be tricked into totally overlooking traffic signs, persons and what not.

content: I still want to see how well a self driving car would do on a typical road in the winter, especially side roads. No lines (covered in snow) to act as guides and no real distinguishable road edges, other than snow banks. Any kind of radar/lidar will have a hard time with that texture I think.In a southern city where the roads are super smooth, and have nice crisp lines it should not be too hard, but it's not like that everywhere.I think driving assist technologies will continue to improve, where the driver can do a bit less of the work, but driverless is a long ways away I think. Then again it's easy to underestimate just how advanced technology can get sometimes.

Expect inwards facing cameras.Quote from: 0xdeadbeef on May 15, 2019, 04:36:05 pmOnly Tesla are relying that heavily on neural networks and they haven't demonstrated the same level of self driving as the others. The Tesla autopilot is basically advanced cruise control. Everyone else is using very good sensors and deterministic algorithms for the basic steering and collision avoidance. They extend here and there with neural networks when it makes sense and is safe. It's ironic that people first think of Tesla when self driving cars are mentioned, based on what they have shown so far they are way behind Waymo and the others.Quote from: Red Squirrel on May 15, 2019, 04:50:19 pmI don't think it matters if the roads are super smooth or not, it all began when the Stanford team won the 2005 DARPA grand challenge and that was a 212 km (132 mi) course through desert. What they have problems with today are things like figuring out the best place to stop and pick up passengers at a crowded shopping center parking lot, etc.They don't pretend to be able to handle heavy snow yet, but there are plenty of places without snow. The cars use the detailed maps to determine where it is to within a few centimeters (without gps) by comparing the map with the sensor data. If everything is covered in a meter of snow the maps won't be of much use though. Even humans can have problems determining where the road is in such conditions. Might be a while before they solve that.From the DARPA grand challenge course:

content: That DARPA challenge course looks like a piece of cake compared to driving through most European cities in the rush hour.And regarding Tesla's "autopilot": It's what other manufacturers had for years but called it something like "lane departure warning system" or "adaptive cruise control".Actually I read a pretty balanced article lately about driving experience with a model 3 and the author stated the "auto pilot" worked worse than similar systems of other (gasoline/diesel) cars in the same price range.Tesla's achievement is mainly to create the impression to be ahead of anybody else regarding autonomous driving even though they drag behind in ACC etc.

After the grand challenge there was the urban challenge in 2007 which the Stanford team also won. Then they managed to convince Alphabet to invest in a self driving car project which later became Waymo. Since then they have focused on driving in all kinds of traffic.https://waymo.com/360experience/

content: My main issue with the common approach of training a system in a well defined scenario is that this implicitly means that anything outside that scenario will cause a more or less unpredictable and thus potentially catastrophic behavior.Like in 2016 there were reports of Google's self-driving car getting confused by cyclists executing a track stand. Now I guess they trained their cars in the meantime to cope with that but what happens if a clown on a unicycle appears next to the car? Or a bear on a unicycle? Or an elephant that escaped from a circus? What if there is a hailstorm at the same time or an eclipse or the road is undermined by water and somebody in a penguin costume is trying to warn people about a rampage?There are just too many unexpected situations that you can't train you system for so you need a system that can actually judge a complex situation just as a human could. Even if it involved elephants or people in penguin costumes. And that is just not going to happen soon.

content: Unpredictable situations are naturally the most difficult. The basic parts of the drive system is deterministic though, it will avoid driving into anything the lidar sees whether it's a bear or someone wearing a penguin costume. Self driving cars don't have to be 100% safe, nothing is. Human drivers certainly are not: "In 2010, there were an estimated 5,419,000 crashes, 30,296 deadly, killing 32,999, and injuring 2,239,000."source. If robocabs are much safer than that it's acceptable if they fail in some very rare cases.

content: Currently, autonomous cars just stop when something unexpected happens - but that is not a behavior that can be accepted in any situation. Actually stopping or blocking a street can kill people in certain situations.Besides, not judging a situation correctly can also result in driving into a truck that was mistaken for a traffic sign or whatever.And yes, human drivers make mistakes as well, but not the same idiotic category of mistakes unless they are drunk or copulating or both.Now coming up with numbers of accidents caused by humans is somewhat pointless as obviously there is no way to compare that to issues caused by autonomous cars given the very few of them that only drive in the brightest sunshine after the track was examined in each and every detail. Actually, taking into account the ridiculous small number, slow speed, ideal conditions and possibility of human intervention, the accidents caused by prototypes are somewhat alarming. Admittedly, most accidents were caused by unexpected braking (i.e. another car hit the dumb autonomous car which was confused and hit the brakes without any warning). But there was already at least one fatality despite of the somewhat ideal conditions and low number of self driving prototypes (which most likely would not have happened if they hadn't disabled Volvo's emergency brake system).

In fact, the last thing I heard from a Waymo official was that the car would pull over and stop if there was a situation it couldn't deal with. That's the same thing a human would do. (And in some occasions stepping on the brakes is the right thing to do.)Quote from: 0xdeadbeef on May 15, 2019, 07:32:30 pmYes, and the same applies for humans. What matters is how often something like that happens, if it happens less often with robocars then they are better obviously.Quote from: 0xdeadbeef on May 15, 2019, 07:32:30 pmHumans both drive when drunk and when copulating (and probably both), they also drive while using their smart phone or when they are too tired or distracted by other things. They also cause accidents when at their best. But in the end it just comes down to who killes fewest people. I don't care if I get run over by a human or a self driving car, what I care about is how likely it is to happen.Quote from: 0xdeadbeef on May 15, 2019, 07:32:30 pmOnly one of Uber's prototype cars have caused a fatality (not counting Tesla since we seems to agree it's not a self driving car).Waymo has driven autonomously over 16 million km (10 million mi) now without causing any accidents. As you rightly point out they have sometimes been hit by tailgaters when the Waymo car did something "stupid" like stop for a red light or a stop sign, but I would argue that is a problem with human drivers not the self driving cars. So the stats are looking pretty good for Waymo. Still, we won't get any real data until they begin driving without safety driver completely, which should happen within the next few years.Some companies should't have been allowed to test their cars on public roads. Uber had not only disabled Volvo's crash avoidance system, but also their own built in emergency brake system (which actually detected the pedestrian in time and would likely have prevented the accident if it was enabled). Why? Because it had so many false positives it was basically broken. Instead they relied on the safety driver who was watching tv on the phone. Other companies normally use two highly trained safety drivers in a car that has so little autonomy.Btw, Uber is now working on autonomous flying cars instead:

content: I reckon it will be a *lot* longer than 10 years before we see autonomous cars - if ever. Don't forget the engineering maxim "the first 90% of a project takes 10% of the time. The last 10% takes the other 90% of the time". IE. The easiest parts are tackled first and the remaining issues get increasingly harder - autonomous driving being a perfect example.Hell, in the UK the 'smart' meter development programme has been running for over 10 years and the costs could rise to £20B - for a bloody meter that only has to count kW hours and send the numbers to a data centre periodically. And it's only just started rolling out meters that meet the current standard. That should be way simpler than autonomous driving - though like most developments benefitting from government direction (interference) it's way more complicated than it should have been.Double hell - I'm still waiting for a house robot that will fetch me a beer and find the TV remote after 50+ years of promises from 'Tomorrows World' etc. How hard can that be?The basics of driving, navigation and situational awareness are relatively straightforward (but not easy). The problem is the myriad of corner cases and unexpected situations that have to be dealt with - the traffic sign that has slipped and is now upside down; the washing machine that fell offf the back of a truck; the breakdown requiring a short reverse down a one-way street; etc. ad-infinitum. If a car stops everytime it encounters a situation it doesn't know how to deal with gridlock will quickly follow.You either have to have a team of very clever people considering how to design the hardware and software to reliably deal with every conceivable possibility and then have some way to handle the unconceivable ones (or much more likely, the conceivable ones that didn't occur to the developers because being hip and eco only use electric scooters and public transport and don't drive). Alternatively you have to come up with something that can self determine the best course of action in every situation that arises. The first would require vast engineering resources, the latter extremely good AI. That may be the answer and I don't know how good the state of the art is but I'm not holding my breath.Some of the more interesting problems will arise from the non-autonomous vehicles co-occupying the roads. Human drivers will have a great deal of fun exploiting the safety first characteristics of self driving cars by, for example, forcing their way into traffic from a side street knowing that the autonomous car will be programmed to give way to avoid a collision. Or pranksters competing to come up with the funniest/cleverest scheme to halt or misdirect autonomous cars by the subtle application of bits of tape to road signs etc. Changes to the law will probably be the answer along with automated reporting of dash-cam footage showing aggressive human driving behaviour etc. but these will take time to implement and both sides will adapt and evolve; but how long will it take?For as long as I can remember there has been no shortage of headlines trumpeting major scientific breakthroughs every few months. But almost invariably, after the initial excitement, it turns out that they've only developed the first 90% and all it requires for the last 10% are a few minor wrinkles to be ironed out, somebody to decide the best shade of blue to paint it, a solution to the Goldbach conjecture and the discovery of some new materials which can withstand 5000C whilst being a bit stronger than graphene at half the weight.Quote from: apis on May 15, 2019, 09:16:02 pmYou might not care but almost everybody else will. People tend to get very excited about deaths caused by things out of people's control and very quickly start baying for blood/something to be done/heads to roll. Rational consideration of cost - benefit tradeoffs won't be at the fore-front of most observer's minds (unless they happen to be engineers). When a human f**ks up and kills someone it's an accident. When something manufactured f**ks up and kills someone because of a design defect it's a company/corporation head that has to roll. Laws will have to change radically to allow autonomous vehicles to operate without the threat of company destroying liability costs arising from every incident involving human injury or death.Case in point: it's my suspicion that railways in the UK are much too safe. The death rate on the railways is extremely low compared to the roads - which is a result of public demands for change after every major accident. That almost invariably means more cost and as a result we have a fabulously safe, but hideously expensive railway network that hardly anyone uses because it's too expensive. Eg. a child gets killed at an uncontrolled crossing resulting in all such crossings to be closed and fences to be erected alongside every inch of track to prevent any inadvertent access. When I say hardly anyone, that's relative to road usage of course - our trains are regularly overcrowded but only account for less than 9% of passenger miles. (Yes I do understand that many of the most important safety improvements don't incur significant costs - but many do.)There are plenty of youtube videos showing the difficulties and problems that self driving cars get into for those interested.

Add the Media into the mix and you are guaranteed to have a reaction a thousand fold greater for one death from autonomous vehicles than a hundred from human driven ones.It's sad to say, but this will only start waning when we get to the point that autonomous vehicles become more pervasive and we as a population can start getting into the statistical comparison mindset thatapishas already expressed. We are several decades away from that, IMHO.

If they die, the EV market goes with it. Teslas are basically the apple of EVs and everyone else is trying to have a similar offering. Except unlike phones, there is not necessarily a huge demand for them so if they go away, that's that. Of course I could be wrong, the other companies could still continue with their own EVs but I feel they are just doing it because they want to have something they can have to compare with Tesla. They can tell a customer "It's electric just like a Tesla, and those are cool right?".

Certainly, it will lose a high profile player, but there are other manufacturers who are in the game to some degree - and with some bold legislative targets in place in some areas and the general tendency away from the love affair with petroleum fuels, it will continue.

Modern computers still have a difficult time of identifying an email as spam, something that a human of average intelligence can determine at a glance with nearly 100% certainty. They work on carefully mapped urban courses but the real world is full of edge cases. Every day I see debris in the road, spilled paint, sand, worn off markings and all manner of other things that will confuse the heck out of an autonomous system. That's before you even consider all the impatient/malicious people who will do things like not allow a vehicle to merge. You have to be pretty aggressive in a lot of areas to merge onto a highway, I can picture it now, this poor self driving car inching timidly forward waiting for a gap in traffic until it runs out of lane and helplessly stops.

content: The argument that autonomous cars don't get drunken, tired or drugged is a weak argument. I don't want a car that statistically crashes less often then humans but fails to handle rare situations a human would have handled. Imagine a tree just about to fall on the street during a storm. A human would see that tree leaning over and stop. But what about an autonoumous car? Autonomous cars need to be able to deal with all situations a human can and more before they can be accepted.So it is not a numbers game. The benchmark must be an intelligent, not speeding, fully aware and sober human driver.

So we humans are still able to drive even if our system is severly impaired. Imagine a self driving car with ram chips falling of the board, lens of the camera defocussed and lidar giving wrong distance readings.

The problem now is only the massive development cost and the cost of all the electromechanical parts, servos, and sensors. It just isn't worth it simply for a curiosity that can fetch you a beer. But there are other areas where an agile robot would be very useful (like military applications) so it is under development. Once the robotic platform has been developed and is being mass produced enough to get down costs we might begin seeing domestic robots doing simple tasks.I'm sure you have seen these before:"We have begun field testing the Spot robot for commercial usage around the world. After an initial mapping run, Spot autonomously navigated two dynamic construction sites in Tokyo and used a specialized payload for surveying work progress. An additional camera in its hand lets Spot do even more detailed inspection work on site. The Spot robot will be available in the second half of 2019 for a variety of applications."Quote from: splin on May 16, 2019, 03:09:28 amThe difference is that this technology have been demonstrated for many years now, there are several different companies developing such self driving systems and companies with very deep pockets are pouring a lot of money into it. I find it a bit weird so many are in denial about it.Quote from: splin on May 16, 2019, 03:09:28 amYou might be right about that, people are irrational, and I won't pretend I can predict what the psychological reaction will be.Quote from: splin on May 16, 2019, 03:09:28 amReally, they are not showing up in my feed.

So identifying spam is a very different problem, reading and understanding text requires a semantic understanding of human life on whole different level, and neither natural language processing nor AI is good enough for that yet. Even so, using surprisingly simple methods, I find that Thunderbird is pretty effective at classifying spam, as are gmail.Quote from: james_s on May 16, 2019, 04:50:53 amDoes Phoenix count as the real world?"Waymo One riders are currently able to take rides within parts of the Phoenix metropolitan area, including Chandler, Tempe, Mesa and Gilbert. Our service operates around the clock, seven days a week. Riders can travel anywhere in our territory day and night."Quote from: james_s on May 16, 2019, 04:50:53 amLast year, Waymo's prototypes drove the equivalent of a year (for an average american) between disengagements in California. I'm convinced none of the things you mentioned would be a problem for their cars. Undoubtedly there are still some unpredictable things that will cause issues, but It's really hard to come up with an example since if we could they wouldn't be unpredictable. What matters is that the problems are rare enough that they are at an acceptable level. Perfection is impossible, also for human drivers.Quote from: james_s on May 16, 2019, 04:50:53 amPeople are nuts, and maybe malicious people will be a problem, but there will be real people in self driving cars as well, and most people aren't sociopaths.Quote from: james_s on May 16, 2019, 04:50:53 amActually that kind of thing has been mentioned before. Similar problems arise in many situations, e.g. when making a turn in an intersection you can't just timidly sit and wait since people will never let you drive, you have to start driving and signal that you are going before others let you pass. But they have solved such problems before (e.g. with intersections) so even if merging onto a highway is problematic (I don't know if it actually is, they wouldn't tell us if it was) I think we can expect it to be solved relatively soon.There's another problem though, sometimes driving in the real world requires you to break the law. I.e. the law might dictate that you drive very timidly but in practice people routinely break it or they wouldn't get anywhere. What should the programmer do in that case? Program the cars to break the law routinely?Something they have admitted is very difficult is figuring out the best place to stop to pick up/drop of passengers. They can't just stop and block all traffic on a crowded parking lot for example, or other drivers would become pretty annoyed.

You should also look at how human drivers can't cope with unexpected situations as well so there has to be at least a single standard as a benchmark. Fortunately there is one... In another thread someone pointed out the SAE has defined 5 levels of autonomy and Waymo (and at least one other but certainly not Tesla) is already at level 4. And they are going to start doing tests without the safety driver which means getting at level 5 (which is full autonomy) is very close. Several years at most and certainly not a decade.

They only sell in artificially created markets. In the Netherlands the politicians are slowly waking up to recognise the fact that EVs simply aren't affordable to most of the people and the CO2 reductions are minimal at best. The latter means that EV subsidies (which already have been reduced) are a large waste of tax payer's money. In the Netherlands sales of the relatively expensive Tesla Model S & X, Jaguar I-pace, etc have already dropped to near zero because the subsidies on these have been cancelled. What is left are cars with a very small range. On the topic of Tesla: Tesla has released a very short range (cheap battery) version for (AFAIK) the Canadian market in order to have their cars eligible for subsidies. Needless to say that a limited range doesn't help broad adoption of EVs due to lack of usefullness as a replacement for a regular car.Edit: link to article about Tesla's short range model:https://www.cnet.com/roadshow/news/tesla-model-3-93-miles-range-canada-ev-incentive/

If they mainly operate in a metropolitan area the shorter range isn't a problem, and it's also not a problem to take cars out of service for charging regularly. They will get lower fuel costs, and be environmentally friendly which is good pr (besides the obvious advantages for the environment and smog levels). You also utilise the cars better, they won't just collect dust in a garage but will be used until they wear out, so fewer cars can service more people.

content: The Waymo routes in Phoenix are carefully curated routes that are mapped to incredible levels of detail and Phoenix is flat with a dry climate. It's nothing like being able to drive to arbitrary locations throughout the nation. The area where I live for example is mountanous with lots of twisty crowded roads and complex confusing intersections that don't meet at right angles. There is a lot of inclement weather, rain, hail, the occasional dusting of snow. The roads are very crowded and getting worse all the time, I think there's a good reason none of the self driving testing is going on here despite the tech industry being second only to Silicon Valley.

content: Quote from: apis on May 16, 2019, 08:07:46 pmI'm as puzzled by those who seem to think autos are anywhere close to reality. Even if they can drive well and if they can park in a space, how will they gofindinga space to park? Is this even part of the programming? I know I use lots of clues to find a spot including looking to see if someone is in the drivers seat and may be about to put their seat belt on. I also look at people with a shopping bag and stalk them in case they are leaving. The cars have to be able to recognise parking signs to ensure they don't park and get a ticket. Who gets the ticket?On the issue of who gets the ticket, that extends to who is going to accept responsibility for loss in the event of an accident? That's the road you have to navigate successfully before autos gain mass acceptance.Going back to the parking issue. Yesterday I was getting into a lift (not Lyft) and the doors were painfully slow to close, or so it seemed because no-one else was around. In reality it was about 5 seconds. A lift still can't even tell no-one is waiting. It still takes a timeout to elapse on the door entry beam not being broken. How long will someone tolerate driving around whilst the car seeks a spot and is outbid by human drivers better able to find a space? Take the steering wheel out of a car that drives well enough to not require a passenger with a drivers license and the car will have to park itself somewhere. This aspect of driving has to be dealt with. It just has to be, but I have never seen any auto do it. Or even attempt to do it.Talk about denial that's a place to start.

content: Why would a self driving car need to park? In many cities driving around on the slowest route will be cheaper compared to paying for the parking space.Besides that many people are really dumb when it comes to finding a parking space. On a lower or upper floor you can usually park right next to the elevator and get out of the parking garage quicker. Instead many people like to wait until someone is leaving a space (causing a traffic jam and delay) because they are to neurotic to look further. A self driving car can take these metrics into account an find the most optimal parking space. In the future self driving cars are likely able to talk to the 'empty space' detection system and drive to the nearest available parking space.

content: Quote from: nctnico on May 17, 2019, 01:09:14 amI've observed that parking lot behavior too. But my point was not just in a regulated parking garage but also in the street and wherever a less clearly delineated cluster of parking spaces exist.As for an auto knowing where a free empty space is, well I'd like to see it argue with a human driver who thinks they saw it first. It will possibly literally demonstrate "punching their lights out".My basic argument is that where humans and autos interact there are situations that are not part of the programmed intelligence of the machine. As long as that remains so then autos are simply robots that need an artificially constrained environment to operate in. They will not be ready for the real world soon. And I am betting the cost will be too high and the world will move past them being a viable option. Other requirements of burgeoning urban development will drive us away from the current car lifestyle. I already see younger people for whatever reason opting to remain without a car for longer than was done when I was their age. Continually spending billions to build expensive and controversial tunnels and other road infrastructure to relieve local congestion bottlenecks can only go on so long. You cannot spend your way out of road congestion and although autos were meant to make roads flow more smoothly that also is a temporary solution. Cities would sprawl a lot less if they didn't need to accommodate so much roads. Cities like villages before cars can only grow to a size that requires a tolerable time spent commuting. It's not distance it's time spent commuting. That time defines the size of the city because it defines how much roads and cars are needed and can fit into the available space. I reckon we'll hit the limits before we develop autos and when we hit the limits no amount of automation will help.

They will have to park at times, but they can then find a spot in a less crowded area. The same is actually true for a privately owned autonomous car, it could drop you off at your destination and then drive somewhere where there are free parking spots. (But I don't think we will see privately owned and operated autonomous cars for a long time.)Quote from: wilfred on May 17, 2019, 12:42:22 amWhile the cars don't rely on neural networks to determine if there is an obstacle on the road in front of the car (that is what they use the lidar for), they do use neural network for a lot of other tasks. Determining if someone is in the drivers seat and are about to leave is a perfect task for a neural network, and Waymo have claimed they can do exactly that. They are very likely not 99% accurate, but neither would a human be, and they don't have to. Neural networks really excel at such tasks, often demonstrating better than human performance.Quote from: wilfred on May 17, 2019, 12:42:22 amNot sure why recognising parking signs would be an issue?

Waymo and GM develop their own in-house lidar systems.Quote from: EEVblog on May 17, 2019, 01:38:24 pmThey can handle light rain, but in heavy rain they pull over and stop. That is clearly not a long time solution and it will probably be a while before they solve that problem. Since the lidar is blinded in that situation (and I don't see how they could fix that) they would have to rely only on cameras and radar, and as we have seen from Tesla, they can't drive safely with only cameras and radar. A lot of progress has been made on computer vision in the last couple of years though and vehicle radar is getting better as well. They will probably get there eventually, but it's hard to predict when, it could take 10 years or 30.

content: Quote from: schmitt trigger on May 17, 2019, 02:06:12 pmI don't think what you describe is a big problem. The computer has much better control of the car than an average human driver, so narrow twisty roads are less of a challenge than for humans. They also have much better situational awareness than humans, a self driving car would spot the kamikaze scooters long before a human, predict their intended route and plan accordingly.

So far Tesla haven't demonstrated anything near the same level of self driving the others are working on. Elon says every one else is stupid for using lidar and detailed maps, but unlike Tesla the others have actual self driving prototypes on the roads, averaging more than 17 thousand km between each human intervention. If Tesla have a fully autonomous car ready for release they have managed to keep it secret from everyone else.That is why I keep talking about Waymo, they are the technology leaders and what people should be looking at when talking about self driving cars.

content: Quote from: radar_macgyver on May 17, 2019, 02:02:18 pmI think so too, if they start providing infrastructure to make it easier for autonomous cars many of the biggest challenges go away. For example, the cars use cameras and computer vision to look for traffic signs just like a human would, but it would be fairly trivial to have a radio beacon to signal the same information. Or you could have whoever is responsible for the traffic signs be required to update publicly available maps whenever they make a change (they probably do that already anyway). You could put iron spikes at regular intervals in the road to mark the lanes so the car can sense where the lane is even if the road is covered in snow. You could have special drop off and pick up points for autonomous vehicles in crowded places, there already exist such special taxi areas outside many airports and train stations.But so far they have said they want to everything without the need for extra infrastructure.

They don't want to pay drivers.But robot or not no-one will like paying to sit in traffic.People, feel free to list out the reasons autos are the future and where the benefits will come from. I don't follow the development of autos all that closely unless the mass media pick up a story but it's not self evident to me where the longer term benefits are coming from for ordinary people.Every day I drive in traffic I see some situation and I think how will an auto deal with it. Simple things like today I had the choice to merge into the front of a tram or fall back and merge in behind it. I could have a driver who doesn't want to be behind a tram in the first place (like me) who doesn't want to make it easy and wave me in. It could be an aggressive driver who has already been stuck and definitely won't make it easy.For those not familiar with trams you can't pass them on the other side of the road and you can't pass them when they are stopped to set down or pick up passengers, And you definitely can't pass them ona busy inner city road where cars are parked and there is no gap big enough in the parked cars for a kilometer. Autos in Melbourne will have to manage it or the fare paying passengers will be unhappy in both time and money. Any driver in Melbourne with any experience with traffic manages to work out the maneuver but I would say it is an advanced skill.

content: Quote from: wilfred on May 18, 2019, 04:12:07 amThe driving motivation behind any company is to make money, that's just how the world is, that is a political issue not a technological. There are lots of people involved in developing autonomous vehicles though, and everyone's motivation might not be as cynical. The reality is that getting people out of the driving equation will save lives. The need for transportation won't go away, and as long as it doesn't there will be a need for drivers. Besides reducing the traffic accident rate you get all the normal benefits you get from automation, lower transportation cost and lots of people get more time over to do other things. If that leads to improvement for "ordinary people" or not (whoever that is) is once again a political issue.QuotePeople used to say a chess program would never beat a grand champion, turns out you could do it in 1996 with a disappointingly trivial algoritm as long as you had enough computing power. Since then the algorithms got better and we got even more computing power and a chess program that beats the world champion runs on an ordinary desktop computer today. To beat Go you needed neural nets, and today it's trivial (if you know how) to beat any human in perfect information games. Neural nets were developed in the 70's but it's not until now it's practically usable, there just wasn't enough computing power before. There have been an exponential growth in computing power that has made things that where impossible a couple of decades ago feasible. I think even software developers have trouble keeping up, exponential change is just too overwhelming and unintuitive.Quote from: EEVblog on May 18, 2019, 07:10:56 amYup, but a lot of people were grossly ill-informed. And yes, completely agree about the continent hopping rockets.But it's probably Musk's bold optimism that makes people like him, and that is an important part of what makes him successful.My point was that Musk isn't exactly careful with the truth though, even if he does some cool stuff, so maybe take what he says with a pinch (bucket) of salt.

content: Quote from: EEVblog on May 21, 2019, 03:05:29 amIt's maybe interesting to note that it was once assumed that the problem of a computer playing chess better than a human would be a milestone in creating an artificial intelligence. As chess programs got better and better because of sophisticated algorithms and databases, it became clear that this was a misconception. So it was decided that playing soccer would be a better goal towards AI as it mimics the cooperation of living beings. I'm not sure if everybody has given up on this idea yet, but I think it's pretty clear that you can build a pretty good soccer robot as well without getting one step closer to AI. Actually, in the last decade or so, hardware for neural networks became cheaper and cheaper so it was used commercially even though the roots of neural networks date back to the mid of the 20th century. Now some marketing genius simply declared neural networks to be AI, but it's quite obvious that the extremely simplified simulation of the model (!) of a few brain cells doesn't make it intelligent.The problem is that many "normal" people fell for this trickery and actually believe that AI has made great progress lately. Indeed most people perceive mathematics, physics, electronics and informatics as some kind of magic anyway and thus can't really evaluate what is possible with the current state of science and what isn't.Still, not everything human beings do can be easily simulated. And the more complex a scenario is and the less well defined rules exist, the more the simulation actually has to become an artificial intelligence. Nobody would deny that some aspects of driving can be handled by algorithms. Even human drivers are not fully "aware" most of the time. It's the short moments of awareness that are so hard to simulate.

content: Quote from: EEVblog on May 21, 2019, 03:05:29 amQuite right, chess is a so called perfect information game, but it wasn't meant as an analogy but as an example of other things that were deemed impossible for a computer to do by many 20-30 years ago. Since Deep Blue won over Kasparov in 1996 it's been more than 20 years, and computer power have continued to increase exponentially. Things that weren't possible then have become possible now, and that is quite unintuitive to many, and maybe why so many believe self driving cars are impossible.Quote from: 0xdeadbeef on May 21, 2019, 09:33:11 amYes, exactly, it was said that you would need full AI to defeat humans in a game like chess (sounds familiar?). Turn's out chess wasn't that hard. Driving is a tougher problem perhaps, but there's nothing magical about that either.Quote from: 0xdeadbeef on May 21, 2019, 09:33:11 amHardly. Deep Blue winning over Kasparov was a surprise to most people. IBM's approach was brute force using the traditional algorithms, which came as a disappointment because chess had been so over hyped that people believed that surely you would need some major breakthrough in AI to be able to solve it. Turns out the old algoritms were good enough, they just needed a little bit extra computing power. To solve Go you needed neural nets, so that was a bigger step forward (but it was still old technology that suddenly had enough computing power to make it practically useful).Robot Soccer is not believed to require full AI. Sure, it's challenging, but it's not the game itself that requires a lot of "thinking", it requires a very agile robot which is a challenging task mechanically. Building a soccer playing robot team requires a wide mix of skills which makes it a nice fun challenge for a team of students.Quote from: 0xdeadbeef on May 21, 2019, 09:33:11 amNo one is trying to make a full AI to drive cars (unless you listen to Musk). Having a self-aware AI in every car would be crazy and unethical, no one is anywhere near creating full AI. Self driving cars will not be AI, it will be dumb machines that can solve most driving problems autonomously. There will be some driving tasks humans can handle better, but there will be other driving tasks that self driving cars handle better. And it's not about who's best, it's about getting the self driving car "good enough" so that it can be trusted on public roads. (Well, one explicitly stated goal is to reduce traffic accident rates, so they will have to be a lot better in that regard.)

Anyway, it's still a very well defined environment with very strict rules and without realtime requirements (turn based like chess), so something like playing soccer on the level of humans is actually much more challenging.Quote from: apis on May 21, 2019, 10:39:40 amOf course the first step is using tiny little robots with small fields and simplified rules. However, the realtime requirements and the nearly endless possibilities in every single moment make this a challenge much closer to autonomous driving than chess or Go. Playing soccer on the level of human players is of course a mechanical/robotic problem as well and by simplifying the robots, playing environment and rules, the problem might be diminished to something than can be solved by an algorithm. However, the final goal of Robocup is to develop a team of independent robots than can beat the human world champion team.Actually, probably nobody can tell if this can still be done by algorithms but I kinda doubt it. Still, a soccer game is of course a very well defined challenge in a confined space with clear rules and therefore much less complex than autonomous driving in a real world traffic scenario (rush hour in major city during a hailstorm with roadworks and what not).Quote from: apis on May 21, 2019, 10:39:40 amWell, an artificial intelligence on the level of a human driverisneeded to cope with every possible situation in a realworld environment as good as a human driver. IMHO, whoever denies this, underestimates the complexity.Quote from: apis on May 21, 2019, 10:39:40 amSelf-awareness is a totally different issue. Of course, at this point, I guess nobody on this planet could answer if achieving true AI is even possible without self awareness or not. Besides, there is no black and white about self-awareness. Also animals have different levels of self-awareness. Then again, it's actually pretty hard to prove self-awareness. You could easily program a robot or program to pretend self-awareness but it would be incredibly hard to prove if a black box AI is fully self aware or just pretends to be.Quote from: apis on May 21, 2019, 10:39:40 amNah, this will never work reliably in the real world. It will work though in a restricted environment but that just doesn't really help for true autonomous driving.Quote from: apis on May 21, 2019, 10:39:40 amA dumb machine will never be good enough to be entrusted with people'e lives on public roads.

content: Quote from: 0xdeadbeef on May 21, 2019, 02:43:33 pmThe strategy part of soccer isn't hard, it's creating a mechanical robot that can match a human that is hard. As I wrote in the previous post we have more than 200 bones, 360 joints, 650 linear actuators, massive sensor arrays, and a lot of parallel computing power that's been optimised over millions of years. It's going to take a lot of time and money to beat that.Or in the words of the first article you linked to:"The tasks involved in playing football, although much more intuitive to humans than chess or Go, are a major challenge for robots. Technical problems of hitherto unimaginable complexity have to be solved: timing a kick while running, identifying the ball against a glaring sun, running on wet grass, providing the robot with sufficient energy for 45 minutes’ play, even the materials that go into constructing a robot can’t disintegrate during a forceful game. Other problems to be solved will define important aspects of our life with robots in the future: when a robot collides with a human player, who can take how much damage? If humans commit fouls, may a robot foul back?"With autonomous driving the mechanical part isn't a problem, because both humans and computers drive the same kind of machine (i.e. cars) which we already know how to make.Quote from: 0xdeadbeef on May 21, 2019, 02:43:33 pmSoccer strategy really isn't hard. One reason go is harder than chess is because the search space is muchmuchlarger than chess, so just adding a little bit more computing power wouldn't have been effective any time soon. Of course, they still used some traditional techniques in Alpha Go, but it was really the neural nets that was the key.Quote from: 0xdeadbeef on May 21, 2019, 02:43:33 pmLet's take a look at how computers perform at imperfect information games that is much more difficult than soccer from a strategy point of view:EDIT: Sorry, I was intending to post this newer follow up video (I'll leave the old one below for those interested)Tihis is an earlier video from 2018:Quote from: 0xdeadbeef on May 21, 2019, 02:43:33 pmA self driving car doesn't need "to cope with every possible situation in a realworld environment as good as a human driver".Quote from: 0xdeadbeef on May 21, 2019, 02:43:33 pm"True" autonomous driving is a red herring, what does it even mean? Humans also drive in a restricted environment; we only drive along certain roads, we try to follow well defined rules and we sometimes (quite often) fail miserably and need help from others to get out of a tricky situation.Quote from: 0xdeadbeef on May 21, 2019, 02:43:33 pmExcept, they already are. People are already testing without human drivers on public roads.

content: Quote from: Mr. Scram on May 21, 2019, 03:37:55 pmThat is definitely true compared to a self driving car, we are limited to using our eyes and ears (and maybe a little bit of feedback from the steering wheel and acceleration/vibration). A computer can use lidar, radar and can use cameras that see in the thermal regions of the spectrum, and have no dead angles. That (and the fact that computers doesn't get distracted/drunk/sleepy/etc) is why I think it is a safe to assume that self driving cars will be able to reduce traffic accidents significantly.

content: Quote from: apis on May 21, 2019, 04:49:40 pmWho talked about strategy? It's about the player judging the situation and making decisions in realtime.Quote from: apis on May 21, 2019, 04:49:40 pmEven in the cherry picked quote, you left have these statements about timing and object recognition. Additionally, a humanoid soccer robot playing against a human (since this is the goal!) would have to predict human behavior - exactly as an autonomous car. It's just that the complexity is much higher for the car as there are so many possibilities for humans and animals and what not to interact with the car.Quote from: apis on May 21, 2019, 04:49:40 pmYou continue to ignore that even a large number of turns with fixed movement rules is a total piece of cake compared to any real world movement scenario.Quote from: apis on May 21, 2019, 04:49:40 pmAgain, that's a virtual environment where nothing unexpected can happen. Letting aside if the computer performs image analysis at all and that the movement control is very basic: also the actions of each unit are clearly defined etc. Agreed, it's real time, but very, very far away from the complexity of the real world.Quote from: apis on May 21, 2019, 04:49:40 pmSure it has to. Else the whole thing is totally pointless and must be restricted to confined areas where the possible interactions with the real world are limited to a degree the dumb car can handle.Quote from: apis on May 21, 2019, 04:49:40 pmHumans can follow rules but also decide when they better shouldn't. If something blocks the lane, a human driver will be able to react in a sensible way. A dumb car will just stop and block the traffic. Now even this can cause deaths if the car is not able to let an ambulance pass.Quote from: apis on May 21, 2019, 04:49:40 pmThe few things that a computer can handle better like brake assist can be added without replacing the human driver. An autonomous car that replaced the human driver has to be at least as good as a human driver in every aspect.Quote from: apis on May 21, 2019, 04:49:40 pmAFAIK that's not even true. I'm not aware of any tests on public roads without a human driver who can take over at any time. And if this driver is not 100% focused, this can result in a dead pedestrian as we've learned.

Chess and Go is much more difficult games than soccer in terms of strategy.Since when was timing harder for a computer than a human?Computer vision is hard which is why self driving cars have lidar so that they don't have to rely on computer vision algorithms for the safety-critical parts. For less critical tasks like predicting human (and other animal) behaviour they use neural nets. They don't have to be 100% accurate in that case and neither are humans so it works well.Quote from: 0xdeadbeef on May 21, 2019, 06:04:53 pmBecause going from discreet to continuous isn't what's challenging.Quote from: 0xdeadbeef on May 21, 2019, 06:04:53 pmNow you're moving the goal posts (pun intended). The difficult part of robot soccer isn't the strategy part, it's creating a robot with similar speed, agility and endurance as a human pro football player (i.e. incredibly difficult). Identifying the ball and other players (computer vision) wouldn't be hard for a robot today either, running and kicking around a ball accurately is. But the mechanics is not a problem for a self driving cars, since we already have the mechanical parts (the cars).Quote from: 0xdeadbeef on May 21, 2019, 06:04:53 pmNo it really doesn't, that is your mistake. It only have to be convenient and cost efficient enough. We human drivers are also restricted to confined areas where the interactions with the real world are limited to a degree the dumb humans can handle.Quote from: 0xdeadbeef on May 21, 2019, 06:04:53 pmHumans can't handle all situations either (not even sensibly). It's not black and white. It's acceptable if self driving cars need human assistance in a small number of situations.Quote from: 0xdeadbeef on May 21, 2019, 06:04:53 pmIt's actually old news by now.Oct 30, 2018:"We’re excited to announce that the California Department of Motor Vehicles (DMV) has just granted Waymo the first permit in the state to begin driverless testing on public roads.This permit is the result of new DMV regulations that took effect in April, which allow companies to apply for fully driverless testing within carefully defined limits, and is the product of nearly ten years of testing in California by Waymo’s team. It’s the first time that California has allowed tests on public roads of fully driverless cars ― that is, without a test driver sitting in the driver’s seat.Familiar groundFully driverless testing is the latest step in the path Waymo has been on since 2009, when we first began working on self-driving technology at Google. Since then we’ve driven over ten million autonomous miles on public roads across 25 cities. California will join our driverless testing program that’s already been happening in Phoenix, Arizona since last year."https://medium.com/waymo/a-green-light-for-waymos-driverless-testing-in-california-a87ec336d657Video from 2017 (Arizona testing begins)Video from 2018 (California testing begins)

Still, even a stupid driver has a strong interest in getting forward instead of just waiting forever. Just watch what happens if a traffic light gets stuck in the red phase. Human drivers will tolerate this for a few minutes and then the first ones will either ignore the red light or turn around or maybe even call the police. Nobody will just stand there and wait forever.

If there is a problem the computer or the passengers can call for help. Operators can then remote control or guide the car until it can manage by itself again, or in worst case send a replacement car and a technician.

If it's commanded to run a red light the car should be able to figure out what a good moment to do so is. This is pretty much how the more recent Mars rovers are driven, minus the traffic lights of course.

What's nice is that all the other cars can also be given the same information, so when they reach the same broken traffic lights they already know what to do.

One of the first things Waymo found out is that adhering strictly to the speed limit is unsafe so passing a red light in certain conditions is probably also part of the algorithm already.And to paint a little bit of the future: With vehicle to vehicle communication chances are the self driving car is already aware of the broken traffic light and may even negotiate with other self driving cars on how to pass the crossing. It will be the human drivers causing the congestion.

It will be telling the car they can safely ignore the malfunctioning traffic light, or telling the car it needs to make an u-turn and take another route. The car will still be driving autonomously, but it will get help with deciding how to deal with those rare unknowns. Latency or even loss of connection won't be much of an issue as long as it receive the new instructions.

content: Quote from: EEVblog on May 22, 2019, 01:33:58 pmWe and others did think about it. That's where the Mars rover story comes in. You don't need to drive vehicles like a remote controlled car. You instruct them to take a certain action and the hardware figures out locally how to do that safely. An example would be to ignore the traffic lights so the intersection is treated as one without lights. Multiple automated vehicles could even negotiate who goes first amongst themselves. The idea is to leave the bulk of the work to automation and have humans take a look if and when the rare exception occurs. Liability doesn't seem complicated. All sorts of life and death decisions are made remotely. Bridges are raised remotely and fatal accidents do occasionally happen. People tend to prefer humans at the proverbal wheel, even if they're not physically present. Automated processes get a lot less leeway.

content: Quote from: Mr. Scram on May 22, 2019, 02:13:26 pmThe Mars Rover is an entirely different thing. there are no rules, and it's not terribly smart resulting in manual control in many situations. From what the Rover driver told me it's not even close to what is required here. It also takes a long time to make a move, find out it barely moved at all and then try again. For remote command of an earth car it actually needs to be aware of every safety rule and be able to manually disable any safety related check. Now let's consider the number of issues an hour and think about how that's handled. We've established these are cases the car failed and NEEDS manual control so how many external operators do we have? Is it really more efficient than people driving themselves? We could require more training for a license for drastically less than all the additional infrastructure for "self driving" cars. Another issue would be that now you have the ability to disable safety requirements from being met who is going to hack it first?

The point was how it deals with decision making, not having a real time operator and unusual situations. You don't need an Earth bound car to be able to deal with all exceptions. Hybrid solutions are viable and much more realistic than expecting a fully autonomous car right away. That's pretty much how much of our automation works. You wouldn't need that many human operators. Apparently the Waymo cars are currently at one intervention every 18000 kilometres.

content: Quote from: Mr. Scram on May 22, 2019, 10:50:58 pmI think you're underestimating how often manual operation is required for the rover. It's not an autonomous vehicle, it's movements are entirely dictated by humans. It doesn't make large journeys WITHOUT intervention because it's so simple and prone to getting off. Maybe the rover driver knows things you haven't read, I don't know. He could also be wrong, I don't know. How many vehicles do you expect to be on the road? Waymo is working in a small known area. Let's expand that to an unlimited area, and what... Millions of cars? Hundreds? Once the area is expanded to the whole planet you're going to have a lot more instances of "interventions" regardless of the number of vehicles. You also can't plan for average, especially when you start out, you plan for the worst case because otherwise there are going to be times where nobody goes anywhere because way too many require manual intervention than was planned. That happens a couple times and demand will pretty quickly go to 0.

Waymo have been test driving all over USA (more than 16 million km / 10 million mi) it's not only in a small known area.They have launched a pilot service in Phoenix that's open to the public, and that taxi service only operates in a limited area ("Waymo One is currently available in the East Valley of Phoenix Arizona, including Chandler, Gilbert, Mesa and Tempe."). The number of km/intervention in the Phoenix area is unknown but likely much better than their average in California. We only know that number for CA because everyone who's testing in CA is required by law to publish their disengagement rate.

None of them expect a true autonomous car to appear for a number of years. Their disagreements are more about whether its 10 years, 20 years or even further away. All they expect to see in the near future are cars operating in very constrained domains, in good weather, and with strict geo-fencing so they stay in well characterised places.

Constrained for sure, but that's a big difference. And they don't need "good weather", they can't handle certain types of very bad weather at the moment, like heavy rain/snow.My guess is that Waymo will launch their service in Phoenix (and possibly other cities) without safety drivers within the next five years. Then they will gradually expand the areas where they operate. It will probably take decades (the years quickly add up) before they can drive all over the US, not to mention the rest of the world. You have to crawl before you can walk, walk before you can run.What they are referring to is full level 5 autonomy, which is indeed at least 10 years off, but you don't need level 5 autonomy to start a robo-cab service in some major cities.

That's the whole point of that. Don't even worry about it in the context of self driving cars. Waymo reports that for ONE area they drive. California isn't particularly known for extreme weather and hard to navigate roads, neither are those areas of arizona. Where is the kansas testing? New york city? Las vegas? We have poor comparisons for the rest of the US nevermind the world. That's my point, I'm not ignoring or misinterpreting anything. You also never answered how many cars you expect on the road and how many remote operators you see being necessary. It's a huge SCALE issue even if the rate of disengagements stays the same as the number of cars goes up. How do you expect they'd deal with hacking once you're required to add a way to disable safety features? What about bad actors as remote operators? Public perception is huge and there are many things that can outright end any chance of self driving vehicles gaining a foot hold in any market.

Sure, but it's also missing the point.The number of operators seems to be made into an issue where I'm not sure there actually is one. If you have one intervention every 16000 kilometres and the internet tells us cabs average 70000 miles or about 112000 kilometres a year that's 7 interventions per year per cab. That's supposing the technology doesn't advance. Let's be generous and say we assume one intervention takes an operator 30 minutes to resolve. Assuming about 250 working days in a year an operator can process over 4000 interventions in a year and therefore service close to 600 cabs. Note that there are no drivers in these cabs that need to be paid. Even if you pay operators double what taxi drivers earn and the numbers are off by a crazy margin you're still good. The scale doesn't appear to be an issue either as it's not as if hundreds of thousands of cabs appear on the roads overnight. We have various cars on the road already which are very vulnerable to hacking. The hacking ship has sailed.https://www.wired.com/2015/07/hackers-remotely-kill-jeep-highway/

What could possibly go wrong?What about package delivery though where there are no passengers?QuoteI agree. Image is everything. Actual safety versus miles driven is irrelevant.

content: Even though the continuing "accident toll" is an ongoing concern, the numbers of cars driven by humans are vast, as are the km/miles travelled, over many years, & in all sorts of road conditions.The vast majority of the trips taken are safely completed.On the other hand, there are a handful of self driving vehicles, some of which have already had accidents leading to death.The argument is "We have operated this vehicle for X number of miles, which is more than the average driver does in Y time, hence, it is safer, statistically."This reminds me of when germanium transistors first started to be widely used.We were told "Accelerated life tests & statistics prove that these devices will have lifetimes far in excess of vacuum tubes----- of the order of twenty years!"When they started to die after a few months to a year, we had to re-evaluate that information!

content: Quote from: vk6zgo on May 26, 2019, 02:34:30 amThere has only been one fatality as far as I know, the Uber accident. The others are people not paying attention when using the Tesla autopilot which isn't a fully self driving car. You have to look at each self driving car project separately though, one can be perfectly safe and another can be a worse than a drunk driver. Only the safe ones should be allowed to drive on public roads.

content: Quote from: vk6zgo on May 26, 2019, 02:34:30 amHumans are fairly terrible drivers. The vast majority of trips are safely completed, but literally millions die each year for very similar reasons. Fatigue, substance abuse, distraction. Getting it mostly right doesn't seem that comforting, especially if it's your loved one.

content: Quote from: FrankT on July 10, 2019, 06:24:17 amWill they be operating on public roads or just ferrying people around a closed circuit in the Olympic precinct?Japan premiered the Shinkansen for the 1964 Olympics so they have some cred. Still skeptical though. The whole autonomous vehicle thing seems to have gone off the boil.

content: Quote from: FrankT on July 10, 2019, 06:30:31 amThat's a good picture. It illustrates what you and I and a child can see immediately as a picture by the shadow of the cyclist inside the hole.Just today the city was cleaning the fallen Autumn leaves from my street. It is a windy day and the leaves are all over the road and filling the gutters. How does that camouflage the road? I don't necessarily think leaves or a picture are serious issues. They certainly shouldn't be or snow and ice will never be overcome. But how does an auto deal with a pothole or any item of debris like a branch that a human driver would avoid. Do autos slow down out of caution?

content: Quote from: Mr. Scram on July 10, 2019, 11:07:37 amI can certainly understand how somebody might fail to understand it's a painting and not a tunnel, especially in poor light conditions, late at night past the bedtime.On one occasion, while I was staying in a hotel, I woke up thirsty in the middle of the night. The curtains were drawn over the windows so it was pretty dark in the room. I decided not to turn on the lights since I judged there was enough light to navigate to the bathroom, have a drink and get back to bed, after all I could see the corridor leading to the bathroom.Three confident steps later I was violently stopped in my tracks when my nose, forehead, and pretty much everything else collided with a floor to ceiling closet. It had mirror front, and what I parsed as the corridor to the bathroom turned out to be a dim reflection of the window behind me.Sure, I was half asleep and wasn't wearing my contact lenses, but still, Up until the collision I was entirely confident that I was seeing a corridor and nothing else.

content: Quote from: wilfred on July 10, 2019, 06:41:58 amFrom what I understand, there will be 2 types of vehicles. One driving within the Olympic Village and venues ferrying athletes and officials around, while robocabs will be running along several routes ferrying paying passengers.
