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 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.

Obviously the horse can still do things that the gas car can never do, and the gas car will always be able to do things the electric car can't do. But they have really different uses and advantages.

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 like to take folks back to the turn of the century when people said 'gas cars can never replace horses because you can feed horses at your house, you get along with them, they're nice.'
