In the case of all the carmakers, there's a certain amount of greenwash. Take Toyota: They were pushing the Prius while they were meanwhile marketing the hell out of the Sequoia and other models with terrible gas mileage.

I'm sure the gasoline companies would love to keep their 100 percent monopoly on transportation fuel.

Oil companies earned a permanent enemy in me when they messed with the electric car the first time around, and I think they continue to do a disservice in making it seem like fossil fuels are cheaper than they really are in terms of total cost.

There are not a ton of people buying cars - cars are expensive. So people usually go for the cheapest car they can get. And if the price of gasoline falls again, it makes the savings that you get with an electric car harder to realize.

Resistance to change is always the biggest obstacle.

I think electric cars can help save Detroit. They reflect good decision-making, and there has been bad decision making in the auto industry for so long, in my view.
