content: Quote from: Ranayna on November 14, 2024, 04:04:52 pmThat was said to be the case at one time. I don't know if its still true. Those certificates are definitely still bringing them substantial income. The problem for the car makers now is the EU, UK, and I assume some other countries, are setting a minimum percentage of cars sold/registered which must be EVs, and the EV market isn't big enough for the trading to work any more. This year's target in the UK is 22% EVs, and total EVs sales, including Tesla's (which are quite popular in the UK) don't add up to 22%. So unless something changes car makers appear to be facing a 15,000 pound charge per car sold. That's going to make those emission certificates super valuable this year. A lot of EVs have been registered without being sold in the last few months, as the car makers frantically try to get the number of EV registrations up, in a market where even large discounts can't move enough EVs.

content: Quote from: coppice on November 14, 2024, 10:54:05 pmActually, there is no requirement for the cars sold to be BEVs. The limit is the average CO2 emissions from new cars sold in the EU. I understand the regulations in the UK are similar. So it doesn't matter what kind of cars are being sold for as long as the average CO2 emission limits are met. On top of this, from 2025 a different (supposedly more realistic) test method (WLTP) will be used resulting in slightly higher CO2 emission numbers compared to the old NEDC method (*). This is why European car makers are now frantically shifting towards (plug-in) hybrids as the market for BEVs seems to have become saturated in the EU.* Both test methods are a joke anyway. Real world fuel consumption is much higher.

content: Quote from: vk6zgo on November 15, 2024, 12:02:45 amIMHO Elon has a more hollistic approach to putting new technology onto the market. He makes sure people can actually use the products and thus create a real market for the products he develops. The Tesla super-charger network is an example. He didn't wait for others to get in action but made sure his products are supported by an ecosystem one way or another.

content: Quote from: coppice on November 15, 2024, 12:04:33 amThat is going to be an epic failure for sure. Maybe the numbers will be met on paper but likely the manufacturers will simply stop selling non-BEV cars if that means exceeding the limit. In the end the UK market isn't that big. The end result is that older cars will be used much longer causing more CO2 emissions (and other pollution) compared to driving around in hybrids.

content: Quote from: nctnico on November 15, 2024, 12:24:46 amPretty sure there's an age limit on cars in the UK. The end result is that the UK fleet is forced to turn over every X years. And if one assumes that new vehicles are incrementally less polluting, then the forced fleet turnover will cause less CO2 emissions over time.

content: Quote from: nctnico on November 15, 2024, 12:24:46 amWhat is happening is manufacturers are increasing the price of ICE vehicles and slashing the price of EVs, for instance, a "delivery miles" VW ID.3 is available for £28k and the equivalent-model Golf costs... £28k. Even though "on paper" the ID.3 costs £35k and the Golf costs £24k. This is good for EV adoption, and for those who really want to buy an ICE, it is subsidising the EV market at the nascent stage. One thing charging infrastructure needs is demand, so putting a lot of EVs on the road is good because it makes the business case for EV charging even better.

And importing used cars is also an option although that option is hampered by the UK driving at the wrong side of the road. But making new cars more expensive, drives prices for used cars up as well making importing from other countries an economically viable route.

The goal is to phase out ICE by 2045-2050 or so, not to totally eliminate it tomorrow. With the average lifespan of a car being around 15 years, if you stop selling them in 2030-2035, that will happen by natural attrition. And then we will wonder why we drove those weird combustion powered cars around everywhere.

I don't remember the model or manufacturer, but it was old, and had a historic numberplate, which you can get in germany if the car is at least 30 years old and is still mostly using original parts.I think that car was significantly older than 30 years though. It at least pre-dated catalytic converters, because that car reeked to high heavens. The stink permeated everything and the filters in my car did nothing.I am not old enough to remember the time when cars like that were the only ones on the street, but i am very glad that these times are over.

It's quite possible that he would have survived in a modern car; even if he had a heart attack for instance, cars have SOS call features that would alert first responders and they may have been able to reach him in time to deliver life saving treatment. Airbags, stability control, ABS, la ne/road departure warning etc. none of which featured in a 60s Beetle, will all make an accident less likely even in the event a driver begins to lose consciousness or is otherwise impaired. VW vehicles made from 2024 will be able to pull over in the event that a driver is determined to be unresponsive (test in real life,marketing video).It is a noticeable trend in fatalities, cars are getting much safer for the driver. The UK has seen a consistent fall in road fatalities, in 1990, there were over 5,000 killed on UK roads, today, it is around 1,600. This is despite population increasing ~20% in that time and average miles driven per person barely changing.

It was dark, raining heavily, heavy traffic, and I was concentrating on what was in front. Just then an insistent buzzer sounded and an unfamiliar light flashed in my peripheral vision - which took my attention away from what was in front.EventuallyI worked out it was because someone in the adjacent lane had come up my nearside from behind and was (allegedly) too close. I couldn't safely have done anything to avoid that; there was traffic on my offside. Effin' dangerous, and the nearest I have come to causing an accident in half a century!Fundamentally anything that distracts attention and causes heads-down behaviour is dangerous.

In the end, if EVs were impractical or unworkable, no amount of politicizing would help, the whole card house would just collapse. And OTOH, if EVs work and make sense, they will replace ICE cars by free market rules. Which is what we are already seeing anyway. But right now we are in a transition period where politicscanhave an effect. But is it worth it, I don't know. Same end result would be achieved without manipulating the market.

MOTs don't change that very much. They just enforce that people don't let things get dangerously bad before taking action. Cars in generally good shape fail their MOT all the time, as a suspension bush may have excessive wear, or a brake disc may have excessive rust (usually the back ones). A car has to be really old, or perhaps very rare, for parts to be unavailable. It comes down to cost. Massive body rust can be a killer.

content: Quote from: coppice on November 15, 2024, 06:30:01 pmI agree. Unless the body is really rusted, you can replace an awfull lot. If new cars become very expensive, it is worthwhile to simply repair / refurbish older cars. Only downside is that fuel consumption is staying bad. I'm looking at buying a different car somewhere early 2025. My options are to either spend 5k euro on the same brand/model car I already have but a less old one with way less mileage or spend around 13k a Toyota hybrid. In the long run the Toyota hybrid will be cheaper due to lower fuel consumption; the difference is around 5k euro. Going for a BEV is way more expensive in my case (15k extra compared to the Toyota hybrid assuming 200k km / 8 years). The higher purchase price (30k for a use one) and charging costs just kills the BEV financially.

content: Quote from: tggzzz on November 15, 2024, 04:15:05 pmSounds like the van had some kind of blind spot monitor. It's a life saving function, as shoulder checks are often forgotten about. Life saving for both the driver and the unfortunate victim that gets caught in the blind spot. Modern systems can detect cyclists and motorcycles as well as cars. The problem with rental vans is you don't have time to get fully acquainted with your vehicle but that doesn't make something like a BSM a bad function.And I am certain a function like in the VW video will have been extensively tested so that it does not engage in the wrong circumstances, like if the camera is obscured. I'd still much rather have it than not, even if there is a small chance of the system not engaging when needed; better to have tried than not at all.Quote from: tggzzz on November 15, 2024, 04:15:05 pmNo, it really is mostly down to car safety improvements. Remember that cars in the early 90's rarely had airbags, ABS, or even significant crash safety structures, as none of these features were mandatory.The libertarians lost the argument, and consumers flocked towards vehicles that offered good safety features, such that it is essentially impossible to purchase a car nowadays that does not have significant safety functionality. Euro NCAP testing, or scoring highly on those tests, isn't actually mandatory -- so you can release a reasonably unsafe car (compared to other models on sale) but customers won't be as keen to buy that model.

content: Quote from: Andy Chee on November 15, 2024, 11:45:32 pmIn the UK there is no relation between MOTs and fleet turnover. I guess only 1 in 10 MOT failures result in the vehicle's end of life. Lots of 3 year old well cared for cars fail their first MOT for a windscreen wiper that smears a bit, or a lamp nobody noticed has failed. If it has been driven hard for 3 years a variety of minor issues might fail it, and get fixed. One of our cars needed new rear brake discs last year, because the car is driven gently, and normal use had allowed the discs to rust to the point of a test failure. It stayed in the garage for an extra day, the discs were replaced, and an MOT certificate was issued. This is what happens with most MOT failures. Cars have to pass an emissions test as part of their MOT checks, so a seriously polluting one won't pass.

The low cost of natural gas from the North Sea pretty much killed off coal for home use in the 1970s, Mostly because its such a PITA to deal with. There was an incorrect claim of a blanket ban on coal in UK. We simply pointed out that is not true. I doubt anyone would bother with the effort of creating a ban, as we just don't use it anyway.

These are not amounts which buy you another car. So far I have not had a catalythic converter failure even with very high mileage.BTW, on recent cars with EOBD, emissions testing is done by reading the car's computer in case the engine warning light is on. So if the engine warning light is off, it automatically means a pass for emissions.

Of course if the car is really in bad condition and the owner has been thinking about scrapping it anyway then failed inspection can be the final straw.

By the time an engine is worn, there are enough lower mileage replacement engines on the market. For my car such an engine costs around 600 to 700 euro. Probably another 700 to 800 euro to have it swapped at a garage. For those seeking corner cases: ofcourse you are smart and don't buy an uncommon car to begin with. The more common a car is, the cheaper the parts are.QuoteThis is the procedure as described in the Netherlands' MOT testing protocol for cars sold after 2005. Reason I know is that on my car the engine warning light came on due to an emissions issue (catalythic converter / O2 sensor issue) a couple of months ago. Since it was about time for the MOT, I read up on what the test requirement c.q. procedure is.Reving an engine for emission testing is a time consuming job as they have to let the engine run long enough so it is hot and even then there is a risk of snapping the timing belt or cause other damage. Back in the old days every garage over here explicited stated (both through a sign and telling the customers) to not accept liability for damage from doing emission testing (especially for diesel engines).

content: Quote from: Andy Chee on November 15, 2024, 11:45:32 pmGoing to try and pick apart this nested quote as best I can..There is an age limit for cars in the UK, but it doesn't work the way you seem to think it does; when a car reaches 40 years old, as long as it had a valid MOT at the time, it is exempt from future testing, and is also exempt from VED.If a car over 40 years old wasn't road legal when it transitioned, it will have to pass an MOT before being allowed back on the road, but will thereafter be exempt.Leaded petrol is not legal to use in the UK, and hasn't been since 2000.Lead Replacement Petrol(LRP) is what you have to use, if your classic really can't handle regular unleaded. This is now only in the form of an additive you put in unleaded from the pump; up until the early 2000's you could get it pumped on the forecourt. It isn't lead-based.Cars don't need to be old for parts to be unavailable; it's no secret that a well known EV manufacturer prioritises parts to build new cars rather than repair existing ones, and they are far from unique in this, it's becoming the norm, and in fairness has been going this way for several decades now, as a consequence of the "just-in-time" stocking practice, and the change in business model which has seen profit move from service and repair to purchase finance.Modern cars aremorepolluting than older ones. This is an intentionally out of context statement designed to grab your attention, but it's true nevertheless; for a given context.Modern cars are heavier and the fashion is for the bigger variants, so even though engines have become cleaner per unit of fuel burned, they need to burn more fuel to move the vehicle.EVs and heavier vehicles in general cause more rubber pollution due to extra tyre wear. This is non-trivial, and tyre manufacturers are having to research less harmful and more durable compounds.In the past, cars would be forced off the road due to chassis corrosion and serious mechanical failure if they survived long enough (80+ thousand miles, unless meticulously maintained). Nowadays, they die mostly due to ECM failure of one sort or another, or mechanical failure of a single part in an assembly that the manufacturer refuses to supply in any form other than a complete (and stupidly expensive) unit.

I don't know what the current UK practice is, but the last time I saw the test conducted they started the engine, then just let it idle for some time while they did other work. When the engine was up to temperature they did a tailpipe test at idle, and with the accelerator depressed enough to reach some specific RPM values. That was a long time ago, but I saw the sensor being inserted in the tailpipe of someone else's car a few months ago, while I was at the garage for something else. The UK government web site says gasoline cars made after 1975 and diesels made after 1980 are checked by a meter in the MOT test. It doesn't give details. I might be misremembering, but I think the car I saw being tested recently was on a rolling road. They definitely use a rolling road for some of the MOT testing.

content: It is a requirement in the MoT test for the check engine light to illuminate on ignition on, which is why every car out there will do that when the engine is not started. Once the engine is started it should extinguish after a few seconds. If the light doesn't illuminate at all, MoT failed.There are definitely cheater devices out there that emulate this, but given something like 30% of people don't know how to find their oil dip stick, I am not too worried about these devices being commonplace. Simply by it being a complicated solution to work around the check engine light and emissions management (like reflashing ECU firmware) excludes the majority of dodgy cars.It seems most cars near the end of their life fail on either a suspension, bodywork or exhaust component. The engine, gearbox and the rest of the car is fine, perhaps not running perfectly, but sufficient to move the car around. I remember some time ago I went to test drive a car that had a faked MOT (the garage/tester must had been paid off or the VIN was fake, something like that). The car drove fine but you could hear the rear shock absorbers were completely gone. And the door sill had rust at the seatbelt anchor point - instant MOT fail and likely writes the car off. I guess despite my general naivety at the time even that car was an obvious heap of crap.
