> I guess switching to EVs isn't really enough For completeness EV apply regenerative braking for a large proportion of use, which is for all practical purposes particle free. Obviously tire wear still applies but brake pad wear is largely reduced So with EV you are getting rid of ICE particulates, CO2, CO, and NO2 (particularly on Diesel engines) and also drastically reducing brake particulate from brake pad wear. And to be fair my intuition is that the health impacts of CO and NO2 is likely far more harmful then tire and brake pad particulates. Having said all of that we would still be better off just having everyone using electric buses or trains within Metro areas at least.
