Hey, I have an idea. Some car manufacturer should come up with a plug-in electric car with a decent range that covers most people's trips to work etc, but it has a gas engine that allows you to also go long distance whenever you need it. Ideally, the car would be fun to drive and feel a lot like you're driving an electric car even when the gas engine is on.
I think GM should pay me a lot of money for permission to use this concept. But, knowing them, they'll come up with an amazing car that meets all these requirements, then fail to market it at all, and ultimately withdraw it from the market just when the market starts demanding this sort of car.
