I watched that doco a few years ago and it is very interesting. it is blatant that the big oil companies and the govt stepped in and screwed the developement of the true electric car. Its a shame for the USA with its bad smog/polloution problem. Their big gas gussling cars use alot more fuel per 100klms than any other country in the world. I think Australia is mentioned in that doco several times as being one of the, if not the, best fuel per mile car makers on the planet.
Thats another reason why the new Toyota cars are so good, they never need electricity to run the battery they have on board because the car charges itself, which is why the 2012 vehicles are so smart and use so much less petrol than any other same sized car on the planet, very impressive.
