I can understand your disappointment, I hope I can give you some perspective on this. Sadly not enough people are philanthropists. However, so long as people are doing good, do their motivations really matter? This fellow is biking to work, whether he does it for exercise or for the good of the world, it still has the same effect. Large systemic change will only come from desperation and struggle, until then I will take what I can get.
I have had seven roommates this year, all aware and understanding of how I can live without a car, none of them have changed their behaviors even confronted with my ease of living, positive attitude, and beautiful bulging quadracepts. Being agry with them would only make my life harder, it wouldn't stop them from driving 8 blocks to school or 12 to the store.
