Green NASCAR?

Does Al Gore watch the Indianapolis 500 race? Millions of people do but do people in Berkeley and Santa Monica?  I don't watch the race.  The thought of watching other people blow out their tires as they race 500 miles doesn't interest me. But, perhaps I am wrong for being such a snob.  Today, the NY Times  reports that NASCAR is going "green".  Given that millions of non-greens watch, this is an interesting cultural experiment.  There hasn't been convincing research studying the "contagion" effect of environmentalism. As I asked many times, "If Dick Cheney moved to Berkeley, would he become an environmentalist?" Does contact with "the other" change your views?
