What does the extra weight do to roads and bridges? Aren't they going to be negatively impacted. We just keep seeing more and more unintended consequences as we do with most "feel good" ideas. Like Socialism. They all look good on paper but they fall apart in the real world.
Someday our electric grid will be able to support more than a few Electric vehicles (looks like Switzerland is going to have to restrict charging your EV this winter. Good luck at 45% starting capacity due to the cold). Someday, our electric grid will be powered by something other than fossil fuels so that instead of driving your coal powered car and thinking how moral and good you are, we won't need to use coal to power your EV. Someday, batteries will be far more efficient and therefore smaller and lighter and take fewer scarce resources (all controlled by China because they, unlike us, think ahead and implement based on self-interest) to build. We could have cornered the market on rare earth metals but we're too nice. Let China do it. They're our friends, right? Someday, maybe it will be possible to recycle batteries without destroying our environment.
Everyone wants to do the right thing and someday technology will make it possible for the right thing to align with self-interest. At that point, the transition will be so rapid, it will make your head spin.
