#412They are still a luxury item, only affordable by a few. Although to be fair new ICE cars are also a luxury item. Most people can only buy used ICE cars these days
That used to be true; it no longer is. In the EU, some of the cheapest cars on the marker in 2026 are now electric. There are a few nice options in the 15K-20K Euro segment. These are the opposite of luxury cars. There are a quite a few new more joining the half dozen or so that were for sale last year. The trend here is that EVs are becoming the cheapest option. A few cars from Stellantis that are available in ICE a…
Way too expensive for most europeans countries and it’s after heavy subsidies from governments. Most people buy second-hand ICE cars and they will do it as long as they can be driven on roads. Stellantis cars are trash and in general the low-cost EV are trash for long travels.

You're not allowed to drive cars like that in a functional society. When you go for your compulsory car checkup it wouldn't pass the required safety standards.
What I think is missing today is a way to challenge someone else's car. A few independent reports should force an early checkup, and if passed soon after the accusation, the accusers should get their own just to have something at stake.
It's missing because letting the minority of Karens harass everyone like that would cause the political will for the inspection programs to evaporate instantly.
Second, places with high touch governments already lose out on business due to registration arbitrage. Your proposal would dump gas on that fire.

The number of ICE cars I get stuck behind from time to time that just REEK is amazing. I’m in a decently well off area too. Some putting off soot clouds, white smoke, nothing visible but clearly not doing complete combustion. Sometimes I wonder if half the cylinders are even working. I’ve heard one car like that is the equivalent of a surprisingly large number of modern ICE cars is in good shape. I love EVs. I’ve had…
Many car enthusiasts remove the catalytic converter for a combination of additional power and/or better sound. It has a massive impact on emissions and what you might be smelling is hydrogen sulfide which is normally converted to sulfur dioxide which is orderless. I should note the power increase may not have a major impact on newer cars where the cat has been optimized to reduce it's negative power impact. Infact a…

White smoke is water vapor. It's a normal byproduct of hydrocarbon combustion and tends to condense in the exhaust at low loads or immediately after exiting the exhaust, especially in colder temperatures, so you'll see a lot of it in stop and go traffic.

Could also be coolant or oil

For every car enthusiast there are probably a hundred poorly maintained vehicles on the road. Black smoke is likely soot, and white smoke is almost certainly an oil leak.
Oil in the exhaust in quantities high enough to produce acrid white smoke is extremely common on a number of ICE engines, like blown head gaskets on E25s (found in most Subarus before their Toyota involvement in 2010) for example
Subarus with bad head gaskets leak combustion gas into the cooling system displacing the coolant. If you run a flat engine low on coolant it will score the upper cylinder walls and the you will have oil consumption. This is fundamental to all flat engines. Oil in the exhaust is blue smoke. Coolant is white.

> Nobody is doing it for louder noises because the muffler portion is what dampens the sound. Cats also act as mufflers, they significantly reduce the sound coming out the exhaust.
I had downvotes on this post until you (and the other car enthusiasts) pointed this out / saw this. HNs lack of knowledge around cars is sort of frightening.
Don't worry, it's just cars. You can trust the rest.

We love privatising the benefits and socialising the harms of everything. If the exhaust had to go through the cabin so the driver got the worst of it, car exhaust would be the cleanest air on the planet within months and/or alternatives to cars would rocket. But as long as it’s other peoples health affected, meh.
> If the exhaust had to go through the cabin so the driver got the worst of it, car exhaust would be the cleanest air on the planet within months and/or alternatives to cars would rocket. This is why forklift trucks and Zambonis run on propane instead of petrol or diesel. If you burn gas, you get no carbon monoxide or unburnt fuel because it runs ever so slightly lean and all the fuel is burnt. This means keeping the…
That's very interesting. I guess it could be a great option for when the % of ICE vehicles is low enough, it might be practical to ban more polluting fuels.
(Edited to add) Hmm actually people are already doing LPG conversions today as it's cheaper. Not sure if all LPGs are as pollution free, though.

Other car companies fucked it up is funny way to put it. Tesla hasn’t made a new car in a decade and the whole lineup is for my 80-year old Dad. I have 2014 Tesla S, my neighbour 2025, same car. Tesla X is from a decade ago, Tesla 3 is basically Toyota Corolla and Y is basically Model 3 that was pumped up a bit to look like a “crossover”
Wow. This comment makes me wonder if really earth is flat.
when I bought my Tesla S there was a lot of head injuries from people turning around to see this new amazing cars. now, not only are sales tanking but the cars look so old and dated that my first assumption when I see say Model Y is “gotta be someone’s grandma”
when was the last time you saw a Tesla and went “oh cool car!”? been awhile, right? Now ask the same question for BMW, Benz…
Re: Adoption of EVs tied to real-world reductions in air pollution: study
#420Something that needs to be pointed out, especially for those who want to push back against findings like this and essentially defend ICE vehicles: Really step back and imagine a world where the modern EV [1] was first to market and a gasoline combustion engine was second . Who would actually decide to switch from a modern EV to gasoline on purpose of their own choice? The downsides of gasoline cars are actually prett…

Anyone who likes the sensations of driving and not just going fast in a straight line. When you show me the equivalent of an EV Lotus Elise, I'll be properly swayed.
