Cars clean the air because the AC filters capture particles
I clean the air because my lungs capture car particles.
That's why I have an e-bike, so I breathe less when cycling/commuting into the city.
Another way electric cars clean the air: study says brake dust reduced by 83%

#32To those wondering about tire wear: "Despite the slightly higher levels of tire wear from EVs, brake dust was found to be more unhealthy, as brake dust is much more likely to become airborne (>40%) than tire wear is (1-5%). So EVs create a lot less of the worse thing, and a little more of the less-bad thing."
Is tire wear worse for aquatic life than brake dust?
Tire wear right now is worse, because tires contain an anti-oxidant that gets oxidized into a compound that is highly toxic to aquatic life.
The work is underway to standardize on a replacement. This time with even more tests.

#34Brake dust is such nasty stuff, yet we place schools and homes right next to the rivers of pollution that we call highways. I'm hopeful that we will legalize the building of less car-dependent housing, but until then at least EVs will help.
Exactly. EVs are a band-aid, but the true cure is simply viable alternatives to driving .
It's the inverse. Bikes are a temporary 19-th century fix for the lack of easily available personal cars.

So obviously and logically speaking, an ICE car of equivalent weight should have the same tyre wear, and we know that's not true - there are some very heavy ICEs around which still manage to do 50k miles on a single set of tyres without any issue. EVs have instant torque from 0rpm and people use it and that's the main reason. Case in point - we have a Volkswagen e-Up, it barely weighs 1000kg, it's pretty much one of…
I agree there are effects of increased linear acceleration, however I disagree with you because of: On many roads you accelerate and brake less often than you go around corners. These two things are equivalent on tire wear given the forces involved: 1 corner at 50kmh with 50m radius. Accelerating linearly at 0.39g (7 second 0-100kmh) to 77kmh from 0.
I don't think that's neccessarily a disagreement? Both things can be true - if you mostly drive on roads with fast corners, the heavier car will wear out its tyres faster. If you drive on roads with lots of start/stop traffic but not many "at speed" corners then the one that consistently accelerates harder will wear out its tyres quicker.

I wonder if this will be like lead in av-gas. Lol.

I'm 99% sure this is a troll, but I hate to see misinformation go uncorrected. If this isn't a troll, you've been misled by fossil fuel industry propaganda, and I'm sorry. While EVs can be heavier, they often achieve high safety ratings due to their low center of gravity and robust battery protection. Advanced safety features are standard. Studies suggest that EV charging, especially when managed, can help stabilize…
It is not a troll. I was talking about safety for the drivers in the car that collide with the EV. They are less safe with EVs on the road. When we have marginal electricity pricing, and electric cars necessarily being marginal demand, then they will ramp pricing a lot for all users , not just those driving electric cars. This far outweighs the benefit of grid balancing services (which this green revolution has creat…

This argument would look sensible if the car industry, especially in North America (but the rest of the world is slowly following suit) wasn't pushing for bigger and bigger and bigger cars, that are inherently safer for their passengers and way more dangerous for everyone around.
You can have BEV and reasonably sized cars. Car bloat overall is way bigger than the EV weight issue.

#38Anybody who ever driven an EV, would have told that the initial scare about brake dust was pure nonsense.
EVs barely use frictional brakes, with regen performing most of the braking action. Frictional brakes only really come into play to slow down from around ~5 mph to a complete stop.
And even that can be eliminated by essentially running the motor backwards, at low torque. This mode of braking is sometimes used on train engines as an emergency braking method.

There is an additive called 6PPD added to tires to prevent them from degrading in the atmosphere, and it has been found that when this thing reacts with ozone in the air it forms another compound 6PPD-quinone which is highly toxic to some fishes. Weirdly enough it's highly toxic to some species of salmon but not to other salmon species.
Presumably there's work ongoing to find an less damaging replacement, but I haven't heard of any.
