The movie "Who Killed the Electric Car" is about General Motors all electric vehicle the EV1. You can get some insight about this vehicle and how popular it was by going to
http://www.wikipedia.org/ and typing EV1 in the search box. At the bottom of the article is a link to the wiki article about the movie and some other links as well.
Edwin Black in his book "Internal Combustion" tells how the corporations defeated electric vehicle development back around 1912. It seems that Thomas Edison and Henry Ford worked together on development of an all electric vehicle at Edison's laboratory complex. When they reached the stage of designing and setting up production facilities at Ford's factory, a mysterious fire broke out at Edison's laboratory complex destroying most of it. They eventually gave up on the project.
Later on, in the 1950's and 1960's, General Motors spearheaded a drive to kill mass transit in the U.S. They succeeded in dismantling light rail and trolley car systems that had provided cheap transportation in America's major cities for over 60 years. This is also covered in Black's book.
Take notice that ethanol, biofuels, and hydrogen fuel cells will NOT EVER solve the problems of high cost, oil depletion, global climate change, or independence from the oil companies. These stop gap measures will NOT save oil, reduce pollution, or save you money. They are designed to preserve the oil companies' profits and the auto companies' profits.
Electric vehicles are the BEST way to save oil, reduce pollution, save money, and still have cars that are fun to drive. Briefly, electric vehicles can provide from 50 to 100 equivalent MPG, even for large vehicles, because electric vehicles are the most efficient kind available. There is little wasted energy in an electric motor.
Most of the gasoline in your internal combustion (IC) engine powered car is wasted in the form of heat. The combustion itself, the friction of all the moving parts, the waste in the complex transmission required, none of it propels the car.
IC engines require oil changes, cooling system maintenance, transmission maintenance, tune-ups, mufflers, etc., and are composed of hundreds of parts that can fail and require costly repairs. Electric motors, on the other hand, contain a comparative handful of parts that can last for years without needing maintenance. They need no complex cooling system, no complex transmission system, no exhaust system, are significantly quieter, and can provide as good performance, or better performance, than a gasoline engine. Electric motors are effectively zero emission devices.
The Tesla Roadster,
http://www.teslamotors.com, gets 135 MPG equivalent, can travel up to 245 miles on a charge, and can go from 0 to 60 MPH in under 4 seconds. The only problem with it is that it is hand built by a small company so its cost is out of reach of many people. Large-scale mass production techniques would reduce its costs significantly. A Chevrolet manufactured in small lots the same way would cost well over $100,000.
The major reason that GM and the other auto companies don't want electric vehicles is because they would then not profit from selling you all those expensive parts and maintenance, not to mention loss of dealer profits, that they get from selling IC powered cars.
