I guess I just don't seem the point. Car manufacturers already see that this is the way to go, which is why we are seeing more electric cars / hybrids from car companies. If the government really wanted to get cars off gasoline, why not raise the gas tax and stop the corn subsidies first? Higher (visible) prices for gasoline would push people toward smaller more energy efficient cars and public transit and it would make people pay for the externalities. Oh yeah.. that's politically unpalatable.
