Compared to used cars and public transit though, it doesn't nearly look as good. I like Tesla, but there is a lot more to be done before I consider their work truly environmentally friendly.
Sure, agreed. Another problem is that cars are quite deadly, and EVs don't improve on that any. Then there's the whole issue of tire/brake dust (it's the majority of local pollution even for gasoline-powered cars).
E-bikes are a much better environmentally friendly solution for most trips. The problem is the road infrastructure isn't there for them to be safe enough yet; we only build roads for cars, and anyone else (pedestrian or cyclist) is at high risk.
A used electric car is better for the environment than a used ICE car, but the only way to get used electric cars is to make new electric cars.
