Yes. However lets consider this: If it meets 80% of the population's 100% needs then its good enough for me. Imagine a ~60% or so reduction in co2 emissions world wide. Sure 20% of people still need their big trucks, but at least not everyone. Not to mention shaving 1000 pounds off the weight of the car not only gives fuel gains, but lowers power requirements to move that vehicle. Now I was going to say... take that, combine it with tesla's engine, and now you have potentially a long-range vehicle, a vehicle that can already do 300 miles on a charge and potentially a gas engine that can charge it up so you get a nice and unlimited mileage as long as you refuel.

Not to mention cheaper cars!!!!!
