What if EVs (actually, any cars) were programmed for geofencing where acceleration is limited in pedestrian-focused areas based on municipal ordinances? Braking wouldn't be limited (so this is more directly reducing tire particles than brake dust) but I think a lot of city braking would naturally fall off a cliff without excessive acceleration.
You probably don't need to go crazy with stuff like that. Speed cameras seem like effective deterrents. When I drove around the UK, speed cameras were everywhere and people generally all did the speed limit or below.
The USA has a weird cultural obsession with being able to break certain laws. We need to rethink that. If we aren't enforcing laws, then we need to get rid of them, if we don't want to get rid of them, then we need to enforce them.
At city speeds, pollution from tire/brake wear is not a function of speed. It's a function of friction (acceleration/deceleration and vehicle mass), which has no posted limits or camera enforcement. The closest thing would be if a cop happens to hear you burn out and cite reckless driving, but I'm not even talking about that level of acceleration here.
