From slide 17 here you can see that the switch from fuelled to electric vehicles is expected to decrease particulates by 60-80% from 2000 to 2040: https://www.

This doesn’t seem like a trivial improvement. Particulates are not the only toxic component of exhaust either; electric cars should produce no NOx, CO or O3 which is a big improvement. It’s also worth noting that brake wear particulates haven’t been a target because historically exhaust-related emissions were so much larger. If we haven’t really tried to fix it, who’s to say we can’t?
