No it's not EVs are 60% less polluting than fuel vehicles, it's irrelevant if you buy it used because it's history is part of its impact.
The over arching problem is there's too many vehicles on the road, most people including Americans when they drive only drive up to 3 miles.
It's simple there is no reason to work and there's enough of us to say "fuck it" and march to change our system but none of us can organise a piss up in a brewery to save our lives.
We have working class people on their knees to the capitalists saying "yes master anything master"
We have socialists who prefer to talk about socialist philosophy instead of action, we have socialists who want bottom up socialism and others who want top down socialism
We have other people on the left that wants to keep the abusive system in place and we have the rest of the working class who don't care about anything.
The problem is literally capitalism
