If our goal is to save the world, the only answer is fewer cars. Drastically reducing the number of cars and roads and instead using public transportation, bicycles, walking, etc. is the solution to so many of our social problems. Even if we somehow replaced every car with a self-driving electric car, and recharged all those batteries with solar power, it would not save us. If you really want to save the world, stop using cars period.
