Tires and brakes still contribute to a lot of particulate matter pollution even from EV's, but they're at least a step up. The best EV's are still eBikes though.

Tires yes, but EVs tend to have regenerative braking which will reduce brake particulates significantly.

The business case is that I will actually buy it. I won't buy "consumer electronics" garbage when I want to buy safe and reliable transportation.

That hasn’t worked for TVs. Or phones. Or plenty of other things.

Not sure what your point is when we're talking about cars, where fixed physical controls are demonstrably more usable and safer for drivers that need to keep their eyes on the road. Multiple manufacturers have pulled back from excessive touch controls (not just touchscreens, but capacitive buttons and sliders) and reinstated more traditional buttons and dials.

tragically, because of efficiency standards, modern engines are known to burn oil . Otherwise you may be smelling cars who have had the cats stolen.

Stolen cars, exhaust leaks before the cat, incomplete combustion so bad the cat can’t cover it up. I assume it’s stuff like that. It’s not whatever tiny bit of oil gets burned in a healthy engine.

Incomplete combustion will ruin a cat. That's not its purpose, it's there to reduce NOx emissions.

I just hope "dumb" EV's become a thing soon. I cannot and will not own a smart car any more I want to own a smart TV or smart fridge or smart toaster.

Have you been in the new Model Y? I was all for the „dumb car” until I tried one of those. Never going back. You only want „dumb” bc the other car companies fk’d it all up.

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”

OK but we already know that EVs don't just move pollution around.

AIUI there are still disagreements about how to calculate that exactly. This study doesn't (and doesn't try to) provide any input towards settling that.

There are no reputable studies that show EVs having anything like the harms of legacy cars. The worst you can get is that if you're on a carbon-intensive grid, a Hummer EV might be as bad as a compact gas car.

It also causes roads to be damaged/destroyed FAR faster due to the vehicales on average weighing significantly more. https://en.wikipedia.org/wiki/Fourth_power_law It also simply moves the pollution to places like Africa where the extremely dirty lithium mining is externalized away from wealthy westerners. Environmental externalization.

Only poorly designed EV's are significantly heavier.

A Tesla 3 and a BMW 3 are about the same weight.

Why? Are you worried from a liberty/privacy standpoint? "Smart" EV's are demonstrated to be significantly safer than "dumb" EVs. Waymo’s 2025/2026 data shows an 80–90% reduction in injury-causing crashes compared to human drivers in the same cities.

Personally I’m not very keen on owning a vehicle the manufacturer can completely brick at will

A lot of old cars also since new cars are so expensive.

Yep. My newest car is over 20 years old. May be a bit more polluting (though it doesn't smell or smoke) but I've in theory saved the environmental impact of the manufacture of one or two new cars by keeping the old one.

I'm not spending $30-40k or more on a car. That just isn't going to happen.

This study is about air quality in neighborhoods . So it would show the same thing even if EVs just moved pollution from where people use their cars to where power plants get placed, because that's not the question it's addressing.

Even if all the electricity for EVs came from a centralized coal plant (it doesn't) it would be better than using combustion in individual vehicles. Centralized pollution in one area is better than attempting to mitigate diffuse pollution everywhere.

A lot of Americans take their cat off on purpose for louder noises. Additionally, a lot of conservatives love to "Roll coal", and literally will shit up the environment on purpose just because they feel schadenfreude from pissing of an environmentalist.

I’ve run into a few of those. They’re generally pretty obvious. Usually a big truck, lots of MAGA & adjacent bumper stickers.

I haven’t noticed people removing the catalytic converters just for noise. The rare time I see a car that wants to be loud it usually just seems to be the exhaust end they changed, or maybe removed the muffler.

The kind of stuff I’m complaining about mostly seems to be older cars, or those in poor mechanical shape. Cases where the people probably just don’t have the money to fix it.
