Seems electric cars produce the same or sometimes more non combustion particulates than ICE cars, eg. bits of road and tire that are flung into the air while driving.

So EVs are better than ICE for air quality, but fewer cars even better.

I think it’s mostly break dust. Electric cars are heavier but can also hopefully mostly use regenerative breaking instead of break pads. Road vibrations (and wear?) tend to go as the fourth power of weight over the axle and so it tends to be worse for (naturally heavier) electric cars but even worse for goods vehicles.
