While fuel efficiency is the main thing for these cars, you have to remember one thing. While they might not directly spit out black fumes from the tailpipe, electricity generation does generate greenhouse gasses (for the most part until we get better with solar, wind, and water electricity generation and storage) We also need to improve our electricity grid in order to increase efficiency.
Or else your towns will be black with pollution and crime will run in the streets...just like Gotham. But don't worry I have faith in humanity.
