Putting EV subsidies instead into electrifying and enhancing train transit seems like a better approach to combat this. A lot of mass transit trains are still diesel powered and pollute heavily (although on a per person basis might be much better than driving cars). I am wondering if a bus is better or worse for tire pollution per capita?
