A lot of air quality problem in cities comes with tyres and brakes. This is why the air quality is so bad in metro stations even though thzy are fully electrical as well. In addition, the policies against car are not only pollution related but quality of life related and urbanism. This is why in many places in Europe you can't build open air parking in cities anymore, it just takes too much of the public space and if yoj want life in the cities you need to be able to walk easier.

Electric cars hardly use their brakes at all due to regenerative braking, so that problem is solved too.

  They use them less and regen primarily alleviates the need for brakes to perform speed modulation when cruising. They're still used for stopping and a bad driver or rapid deceleration will still put excessive wear on brakes.

    > regen primarily alleviates the need for brakes to perform speed modulation when cruising This isn't true for me. Maybe it depends on the strength of regen in your car, but 90% of my deceleration when stopping is handled by regen. I only use brakes under 5 MPH in most circumstances. And I wouldn't say I'm a timid driver.

      How do you know when your car engages the brakes vs using regen? Are you taking your foot off the accelerator and then waiting until the very last moment to step on the brake pedal? I know that Tesla's have aggressive regen, I own one, but it doesn't bring you to a complete stop so you're using brakes at every full stop.

        Yes, I normally do not press the brake pedal until I have already decelerated to about 5 MPH, when regen basically stops. I know that some cars automatically apply the brakes as part of regen to make the transition smoother but I'm pretty sure the Model 3 does not.

        That's a long run out. I try to avoid annoying people behind me by doing that.
