if we were willing to make and drive slower, lighter cars, and adapt our cities to them, we’d already be there. but so long as electric vehicles need to have equivalent speed, range, and size as big gas vehicles, they’re gonna need a lot of heavy batteries. the lithium batteries we’ve got nowadays are crazy efficient in terms of energy stored per kilogram, but the cars demand so much energy. i’d love to be able to replace my car with an NEV, but alas, i legally would not be allowed to even go to the nearest grocery store with it, let alone my job.
