I also think it's a very good one. Electricity is energy, but a cleaner one. All the resources of this planet such as gas will soon be finished, and then we will need some different kind of fuel - electricity is a great one! You can get it from almost everything... I'd definitely buy one of these kind of cars when I'll have the money. I don't need a car to beat light-speed, nor one to refuel every street corner :|
