What is the future of cars?

John DeLorean: There are some exciting things going on with hybrid technology (an internal-combustion engine combined with a second energy source). But don't count out gasoline as the main fuel--because of the multi-jillion dollars that have been invested in its production. The resources for the foreseeable future are out to 60 years. So, I don't think cars are really going to change all that drastically; after all, they've hardly changed at all over the last 60 years. The major innovations have been very few--air-conditioning, power steering, power brakes, and the microchip.
