As far as I was aware, the environmental impact is still considerably less than a ICE car, even if powered from dirty power. The impacts are different, making a simple comparison difficult, but generally EV win out.
I’m not saying electric cars are perfect, far from it. However, the change is pushing in the right direction. Think of it as a 2 front battle. Public transport Vs car, and EV vs ICE cars. Your arguments have very little bearing on the public Vs private transport argument, but heavily affect the EV Vs ICE argument.
I’d strongly prefer cities with public transport so good that there is little need for cars etc. However, I would also rather have a city with EV cars over ICE cars. The change over from ICE to EV will also help change habits. That is a perfect time to push public transport into the mix.
Picking a fight with EV is just going to leave both groups bloody. Big oil etc will egg it on, while laughing all the way to the bank.
