This is an interesting question. Actually, electric cars have been around much longer than what you suspect. Back in the 1830's, an inventor named XXXXX XXXXX invented an electric 'carriage.' From that point on, there were many experiments with electric vehicles, and in 1891, an Iowan named XXXXX XXXXXon produced the first working electric car in the USA. By 1897, the city of New york was actually using electric taxis. In the early 1900's, a good share of the cars on the road (which wasn't very many) were powered by electricity. In 1908, Henry Ford came out with the gas-powered Model T. Drivers preferred the gas-powered version of cars because th electric ones had to be hand-cranked. From there, the gas powered-ones became the norm.
In the 1970's, people became interested in electric cars again because of the shortage and expense of gasoline, but the cars never became popular. There is no way to prove that the oil companies set out to ruin the electric car, or that any cars were destroyed, but there are persistent rumors about this. Here are some websites where you can read detailed histories of electric cars:http://www.pbs.org/now/shows/223/electric-car-timeline.htmlhttp://inventors.about.com/od/estartinventions/a/History-Of-Electric-Vehicles.htm
