The Prius, thus a commercial success, still uses gas. I can't help wandering how in 2001 a hybrid car consuming gas is considered as an innovation while back in the mid 90's, fully working electric cars were working perfectly?
Well, the answer relies in the documentary below, Who killed the electric car?. This documentary was produced in 2006 and explains in details how the powerful petrol and automotive lobbies, along with the US government, put a full stop to the commercialization of the General Motors EV1 car (picture above). I'll let you judge by yourselves. Enjoy this 1,5h documentary film (divided in 10 episodes).
