Don’t forget that EVs use regenerative braking heavily, which generates power instead of brake dust.

They still rely on friction brakes. Especially at low speeds and/or heavy braking, which is what most braking in cities is. Also because of the extra torque a more jerky driving style is possible. I'm really sceptical that current EVs make any real difference to brake and tyre particulates. Drivers of manual petrol cars can already reduce their brake dust by using engine braking. If one drives very carefully it is possible to not use brakes at all. Indeed it should never be necessary. Any time you hit the brakes means you were going too fast. But how many people drive like this? Barely any. Instead people speed right until the last minute then slam on the brakes. Then as soon as the opportunity arises it's heavy acceleration until the next slam of brakes. Driving EVs like this will produce just as much brake dust.

  No, most of EV braking in the cities is regenerative.

  When I had an EV, I had rusty brakes even after my commute. That’s how little I used my brakes. I used regeneration braking exclusively except for rare circumstances where something unexpected happened. Eventually I had to brake on purpose a few times to keep my brake discs shiny, because the rusty discs looked awful

  My understanding is that at least where I live most remotely reasonable people use engine braking in city driving almost exclusively. Indeed needless use of the brake pedal is regarded as a sign of a poor driver. But other countries may have different driving cultures…

    Not that I've noticed here in Australia. Personally, my current car is an auto, and trying to engine break just isn't very effective without switching to manual in my car. Engine breaking can also be noisier, as may have to shift down gears in a way that means the engine revs relatively high, for a brief time - making it a more noticible noise. Out in the country, and for me that often means the hills and mountains, then engine breaking is a much bigger part of my driving style, esp down hills! Engine breaking also doesn't cause your break lights to come on, and they provide a quicker signal that a car is slowing, than relying on people to detect the change in speed.

  They still rely on friction brakes. Especially at low speeds and/or heavy braking, which is what most braking in cities is. I've been driving hybrids for the past five years and in my experience even in heavy traffic friction brakes aren't used nearly as much as in regular ICEs. There's a constant, thin layer of rust on my rotors that I just can't scratch off in any way short of braking on an off-ramp on a highway. I imagine EVs, having overall better regenerative braking, rely even less on their rotors.

  No. I've always owned at least one manual transmission vehicle, but the EV does an order of magnitude more regenerative braking than any passenger car internal combustion engine does.
