Who killed the electric car

This is an great documentary on electric cars. Some interesting facts:

• The GM EV1 was a leased vehicle and when GM stopped making the cars they refused to sell any of the cars to their owners. All the cars were scrapped.
• Major oil companies are proponents of hydrogen cars even though they will not be on the market for a decade. Electric cars work now and continue to improve as batteries improve.
• Chevron Oil owns the patents on Nickel Metal Hydride batteries.

While this doesn't point to a smoking gun, it sure makes you think about fair markets, big business, and the development of disruptive technology.
