Buying a hybrid car because you want to save money on gas - acceptable

Buying a hybrid car because you want to help the environment - misguided, but acceptable

Buying a hybrid car for the above reason so that you can pass judgment on people who drive what they want - fail. The 2% pollution difference is offset by the smug idiocy coming out of your mouth.

Are there any environmentally conscious people out there who don't do it to be self righteous? If there are, I applaud you.
