Jay Leno predicts demise of vehicles running on gas.

I agree with Leno EV will take over. Yes getting the infrastructure in place will take time. Teaching the public a new way of life will also take time but the internal combustion engine is a dinosaur. Too many parts.
Lots of heat loss, just too inefficient.
Technology has caught up to the internal combustion engine, a better mouse trap is here. The heavy lifting for the most part has been done. Now its a matter of logistics and attitude.
