I wonder if this will spur mandatory regenerative braking in all cars, eventually, as a means of reducing pollutants?
You can gear down in a manual transmission ICE to achieve similar reduction effects, but I doubt they will bring back manuals.
Dust from car brakes more harmful than exhaust, study finds

Re: Dust from car brakes more harmful than exhaust, study finds
#12Having lived next to a semi-main street through a smallish California coastal city without much rain it is pretty eye opening how much black dirt and junk just coat everything next to the road.
Walk down the street and touch a bush or any plant leaf and get a nice black hand in the process. The plants are covered, parked cars get covered and the inside of my apartment was covered.
It wasn’t until I moved out that I saw the extent of the problem. I only lived there a few years but every surface of my apartment had a coating of the same black dust. I’m now very worried my short time there considerably affected my health.

#13I think this is missing out on the big issue - tyre pollution which contains really nasty chemicals that inevitably get washed into rivers and waterways. Also, car-shaped EVs often use regenerative braking which will reduce the amount of brake dust pollution, but with their increased weight and powerful torque, they produce a lot more tyre pollution than ICE vehicles. https://earth.org/tyre-pollution/
This study is looking at the health effects, not particle count per mile of car use. A similar study looking at tire dust would also be interesting.

I think the key is to make a class of light-weight EVs with smaller, lighter batteries for life around town. Most of us rarely drive more than a few dozen miles a day.
But then there are those weekend trips.

Yes, the quantity and hazardous nature of different forms of pollution does need to be taken into account.
Unfortunately, tyre pollution seems to be more hazardous and produced in greater quantities:

Those are called e-bikes

This is fake news. The backing study for this claim did all sorts of wonky unrealistic testing to come to this conclusion. If you own an EV, you viscerally know it's BS given that you're the one paying for the actual tire replacements on your real-world driven vehicle.

#18I wonder if this means another advantage for EVs in terms of environmental friendliness.
i feel like only if they make lighter EV's along the line of an i3. A 7-8k lb cybertruck or rivian probably eats brakes like no tomorrow
Re: Dust from car brakes more harmful than exhaust, study finds
#19One solution could be to require ceramic brakes which produce far less dust and may be more environmentally friendly, and even has greater performance which EVs will need for their extra torque.

#20Regenerative braking FTW!
