Several years ago they made a left-wing documentary called “Who Killed the Electric Car?” It appeared to have been filmed almost entirely in California. The bulk of the citizens interviewed sincerely seemed to believe that some sort of Eeeeeevil conspiracy was at work and Gubbermint needed to intervene and put a stop to it.
“Who Killed the Electric Car” is available on Netflix, and I know for a while you could see it in chunks on YouTube (not sure if it was put there ‘legally’ or not, but it was there at one time).
Also, the Chris Paine’s follow-up movie, “Revenge of the Electric Car” has been making the documentary film circuit rounds. More info here:
