I can tell you that when I was shopping for my car, one of the salesmen made a comment that bothered me. He was trying to convince me that there's no reason for me to buy a hybrid, unless I was I was an anti-war activist or some sort of green nut. I thought the comment was uncalled-for, and said nothing to him about it.
I bought my hybrid from a different salesman who didn't try to sway me one way or another regarding which model car I wanted. I bought my hybrid from him because he actually had some knowledge about how the dang thing works.
Personally, yes I am definitely "green", having belonged to several environmental organizations since the 1970's. My reasons for choosing a hybrid certainly have something to do with my environmental convictions, but I also made the purchase because the car can save me a lot of money on gas, and I think the technology is wonderful and should be applied to a lot more cars.

If you're not part of the solution, you're part of the precipitate.
