Addressing to the points about just how green "green" cars are, Bill writes:
This article points out that an electric car burns coal for power-- if that's where the electricity comes from.
Of course, far too much practical environmentalism is really just relocating the pollution to somebody else's back yard. An electric vehicle is excellent for this; you can have a nice clean car in SoCal and the pollution is emitted in one of those honkin' huge coal fired power plants in Nevada that I seem to remember driving past last time I drove out that way-- which was a long, long time ago, so if I'm wrong, I'll gladly let you correct me. "See me, I don't pollute!" And the smoke darkens the sky a hundred miles away.
