The electric sports car that proved such a thing could even exist is being taken off the road.
Tesla announced it will stop taking order for its sleek Roadster electric car in the U.S. within the next two months to focus its energy on bringing an electric sedan to the market.
Despite never being produced en masse, the Roadster, which cost $109,000, served as an important benchmark for automakers to proof that electric cars were a viable alternative to gas-running automobiles.
Former General Motors vice chairman Bob Lutz has said publicly that the Roadster served as his company's motivation to develop the Chevrolet Volt electric car.
Tesla only sold 1,650 Roadsters worldwide as of April 2011. The company is expected to release its type S sedan at a lower price in 2012.
