Why? Why isn't more public transit, which in ever study is massively more greenhouse gas efficient than electric cars and is also already an existing and proven technology a better option? Why aren't plugin hybrids a better option? Battery electric vehicles require massive emissions in assembling a Li+ battery of that size. Given that most trips for people are short distances that wouldn't end up using the fuel tank of a plugin hybrid, why is encouraging their adoption not a better solution. There seems to be a belief that BEVs are the obvious and accepted solution to the climate crisis that I don't think meets muster.
