However the facts of the matter are such:
Gasoline is only ~15% efficient. Gasoline is assumed to be past peak oil - hence prices must rise with time (look at your local petrol station). Battery tech on the other hand falls in cost by 5% per year. Electric engines are 92% efficient - batteries fall in cost 4x over next decade - EV cost/range parity will occur by 2018.
Give it 5 years and they'll be electric Toyota Corolla's rolling around with middle class drivers behind the wheel.
