So your car runs on electricity eh? And so you don't need to put gas/petroleum in the tank. Great. Er...where does the energy come from to charge the battery. Probably from burning coal or gas. The answer is less cars on the road, not more. Less motoring. How to do that? Change suburbia, how we live...and redeploy public transport, especially railway. You may think it's an interesting idea. It's not. It's the ONLY alternative.
