And it's a lot easier to capture pollution at the source of centralized power generation vs hundreds of million of cars, but I am just stating the obvious here.
If anything, your "counter points" -- while acknowledging the tech isn't perfect, are actually making a strong argument for electric cars.
As far as gas vs electric infrastructure it's genuinely perplexing that someone would argue for the former over the latter. For one thing, electricity is a lot more useful than gas! It's also safer, easier and cheaper to transport.
It also exists basically everywhere, even if the current infrastructure is not up to spec, you can still charge an electric car with a regular outlet with no special considerations.
Every thing you are saying is a detraction is really just pointing out solutions that are still in the early stages, but absolutely will get here vs problems we have just accepted from ICE.
