The last conspiracy theory I read said that Shell holds some kind of authority over the introduction of alternative fuel cars on a grand scale. In other words, Shell has nationwide authority (given by the federal government) to say hydrogen/etc cars can't be released to the public (except on small scales or something). Oh, and if you argue that hybrid cars are "alternative fuel", look at the mpg ratings of some of 'em...pretty pathetic, really. Hell, my old '85 CRX used to get 45mpg on the highway
I never saw any confirmation of this conspiracy theory, though. Which probably backs up my theory that it's just horse shit..but still..I wonder why, with today's technology, we still drive cars with a mere 28mpg.
For fuck's sake, we've put men on the moon, bigger boobs on women, and made someone as stupid as Paris Hilton really really famous..
but we can't produce a 100mpg car? nonsense.
