Nah, there’s certification and usually contracts with municipalities for response to emergencies.

It’s a real mix though... paid fire dapartments, volunteers, and private operators all respond to emergencies.
To the extent this works anytime soon it will be so slow and inconsistent that it won’t be economically successful. Any driving service that works worse at night, in bad weather, or outside small well-mapped neighborhoods will not be comprehensive or reliable enough to be economically viable.

Also the idea that self driving cars will end traffic is a dangerous lie to tell. Self driving cars will do nothing to reduce traffic. If anything, self driving cars will increase car trips. And in fact in order to serve people with reasonable service times there will need to be _more_ cars on the road at all times which will more than soak up any additional capacity gained from tighter traffic patterns on restricted access highways.
There are a lot of private ambulance services in the US, they're anything but unregulated though as you'd expect with anything in the US medical field (one of the most regulated industries on earth).

There's no theoretical reason why Uber couldn't get into the driving side of the business, with human drivers. Their future is in autonomous however, which will never be the ambulance business (it will never be autonomous, ambulance drivers frequently have to break standard driving laws in emergencies, drive at high speeds, drive around vehicles, etc).

What do you do with decisions made from the Meeting?
> How should the human driver communicate with the machine?

In theory, a self-driving car could watch for hand-based turn signals, just like a human driver could, and take those into account.

In practice, what someone signals is far less interesting than what they do, and all it does is provide hints for reaction time, which 1) a computer already wins at, and 2) a computer should always leave enough time for braking/stopping/etc anyway. A human driver should never make an assumption based on someone's turn signal that would lead to a crash if they don't do what they're signaling, and neither should a computer.

> What should the machine do when there is a dog standing in the middle of a street?

Don't hit it (stopping if necessary), and listen when the human in the vehicle says "stop" (or "call animal control", or any number of other reactions). The human in the vehicle should always be in control of the high-level actions, just not the moment-to-moment ones.

> Going really extreme: in a car accident in a somewhat remote area, the driver might be able to get an injured passenger out if the passenger stuck. Now a fully autonomous car, there is only passenger.

Not sure what scenario you're getting at here. If you mean a driver and passenger in the same vehicle, the same problem exists today with an injured driver.

The HTML part of this spec is strange. Most of the practical point of markdown has been to allow a limited set of user-controlled formatting without requiring an HTML parser in the browser. Furthermore, HTML has non-significant whitespace whereas markdown does, so mixing the two will give weird results.

Yes, it is. The difference is that I generally choose to listen to specific types of music (or to see performances that I willing choose to let manipulate me). If a random person on the street came up to me and started playing any sort of music, that would be incredibly rude. (Note that this is different than buskers who are not generally targeting a specific person and generally need a permit to perform in a specific place.)

I don't think level 5 would be the next step for self driving automation. The biggest ground based fleet with very high autonomy is John Deere. Therefore, I would expect large commercial trucking to be the next logical target. It would cut their costs alone by changing how much their insurance policies and general efficiency. John Deere trucks almost drive themselves.
So, I would see trucking be replaced first. It looks like Elon Musk wants to do that with their new set of Trucks. Since they would have the same sensors as the cars that would be a bunch of data to collect. It would also be a easier way to get proof of progress. But, at this point if you replace trucking you will get a large economic change because you are changing one of the largest source of jobs in America.

Then since you have proven that you could try acquiring Uber and or Lyft at a fire sale price because they couldn't come up with a solution in time and get their data and logistics.
Who ever gets self driving down first can get as many cars are they want. Two scenarios:

>> I remember the first time I heard To Pimp A Butterfly. I instantly got the feeling that this was made for us (AA).

I think, more importantly, it was also made specifically for white folks who needed to hear the message.

Sure, everyone I know in the AA community knows Kendrick...but they’re also already vehemently aware of the issues.

I’m glad TPAB had the reach it did. Not only is it, message-wise, one of the most important pieces of media in the last 10 years at least, but from a compositional, production standpoint, it still has yet to be surpassed. Many will try. I’ll be shocked if any succeed for the next decade.

What TPAB does, for white folk like me, who can’t directly relate to the message, is prove that we should be acknowledging these issues from the white community...as some of the most talented African-Americans in the world got together (Dr. See, Pharrel Williams, Flying Lotus, just to name a few?) to just project this hyper-clear message to everyone - the African-American community is intelligent, brilliant, socio-politically aware AF and are fully capable of putting forward a message in a far clearer way than I’ve seen most white folks do in the last decade.

I mean, let’s face it. Can we name one album from all the top 40 white producers or musicians that has meant half as much in the last ten years?

This is the most important message that TPAB brings.

For all the damage hip hop did to the AA image in the early 00’s, it’s worst era by far, TPAB is undoing.
It kind of feels like someone made a fairly well-intentioned simulation, and then some other people came along and hacked it for their own benefit, taking away a large part of the value proposition, and leaving a mildly shitty simulation for the remaining people. I guess that sort of thing would be inevitable.
Once automation gets good enough it'll probably be better at it then human drivers (imagine weaving through traffic, that sort of thing. It would also be able to do things like reroute in real time to avoid congestion.

You'll still need warm bodies in the back for life support, but I see no reason that the human in the front seat can't be replaced by sufficiently advanced technology.
I was astounded at the cost of the new Belarus nuclear power plant being built by Russia near the Lithuania border.

2,400 MW of power, for $11 billion to build it. Based on the size of the Belarus economy (GDP per capita), that'd be like the US spending $120 billion to build a new nuclear power plant.

> This really is the endgame for both Uber and Lyft.

I believe so too, but from a slightly different angle: I believe self-driving vehicles will literally mean the end for both Uber & Lyft (and they only accelerate their fate by investing into it).

To understand why: their inherent value is their ability to match human drivers with customers. They both do such a good job at it, that the switching costs between the 2 apps are quite low (first sign of weak competitive advantage).

Now, take away the difficult problem of finding human drivers at the right place and the right time. You now have self-driving cars that make no mistakes, have no scheduling issues, do not get tired etc. It’s way easier to fullfil demand. But, you’re not the only one working on this problem. Google, Tesla, (probably Apple too) are all actively working on the same problem. And they probably have 10X the computing/engineering/cash/data resources to solve this problem.

What are Uber/Lyft left with? A fancy app with a button (which they have already proven to easily clone). Not only that, they also have to compete with the native operating systems (and future devices) that the big corps control. They don’t even own their maps!

So yes, in 2023, you will probably be able to order a Level-5 self driving vehicle to your doorstep with a wink of your half robotic eye, but it will not be Uber or Lyft.

> Their future is in autonomous however, which will never be the ambulance business (it will never be autonomous, ambulance drivers frequently have to break standard driving laws in emergencies, drive at high speeds, drive around vehicles, etc).

None of these are reasons for ambulances to not be autonomous. If you accept that most other vehicles will be fully autonomous, ambulances do not require anything further extraordinary to also be autonomous. The vehicles on the road would likely be networked, at least within a nexus of proximity, and move out of the way of the ambulance so it could speed past them.

NB: I’m not saying ambulances will be autonomous. I’m just saying that if everything else is, the ambulances have no significant (technical) obstacle for also being autonomous either. A significant theoretical advantage of fully autonomous vehicles is not simply that the modal vehicle is safer than a human, but that a networked and autonomous fleet is hyper-efficient and hyper-aware as a hive mind.

I was just thinking recently about how great it was to be in high school. Few responsibilities, spent lots of time with friends, homework and work were easy. Of course, then I remember I couldnt live alone, had little money, homework and work seemed hard because I had nothing to compare it to, drama at school, etc. And try meeting up with flaky teenagers without a cell phone :P

Of course, if you find yourself feeling stressed out by the connectedness, by all means take a break. You don't need to check email or be on slack all day. But at the same time, don't get too stressed out thinking we've lost something without gaining anything. You have the option to turn your phone off, you haven't lost anything. But it is now easier than ever to keep in touch, geography is even less relevant.
