Sure, ICE cars cause more air pollution than EVs. But things like public transit tend to create even less, since there's not a need to have one vehicle per person.
Since public transit makes so much sense in dense cities compared to EVs, I think a lot of the frustration and down votes you face are due to that issue: why replace one known evil with another, when we have much better options available??
Yes you got to push alternatives.
But at the same time, at least 90% of the cars - and near 100% of buses - that are still going to be sold (no matter how one might wish for new cars not to be needed) should be _electric_ ones.
I live in a sprawled out city (Melbourne, AUS), where, especially if you have kids, a car is close to a darned necessity. So those cars are still going to be sold, and far too many of them are dirty gas guzzlers.
I like to walk and ride as much as possible, but after making the move to an EV myself (near 100% solar powered for half the year, then coal the other half - still way better than oil if you look at the whole CO² emission chain) it's amazing how sensitive I've gotten to petrol and diesel fumes.
We have one electric bus in my area. Absolutely awesome to see this first step. Yet a significant number of our trains are still using diesel - their fumes on that (Spencer Street) main connecting station are ridiculously toxic. There's just so much work to do..
Subways have wear-related particulate emissions too, with the added disadvantage of them being less easy to vent: https://nyulangone.org/news/pre-covid-19-subway-air-polluted...
