Degosa,
No argument from me that a electric motor in comparison to a gas engine is a far superior propulsion devise. But the problem has been and still is battery energy storage (vehicle range), charging time, and the fact that everybody does not live in a house, with a driveway and garage to set up a charging station. For those without a garage and driveway. a electric car is not a option even if they so desired to have one.
A electric car maybe viable for those with a garage that can afford a expensive second car for in town commuting.
