Ever since the 1970's when the price of oil quadrupled and ruined many economies, people in high places should have thought that this could happen again at any time. We are now over 30 years past that time and the efforts of car manufacturers to come up with alternative energy cars has been abysmal to say the least. We are supposed to be in a technological revolution, but cars don't seem to have benefited that much from it. The price of many of the cars that run on other fuels is way beyond what most people can afford. Also, any saving in fuel costs would be lost on the initial purchase price. Currently, the government is offering incentives for people to save energy on their homes. Why don't they subsidise alternative energy cars?

A necessay option. The sooner these alterative are available the better I say.
