I'm fortunate to live in a city where attitudes like that are rare. I know many Prius owners, none of whom brag about how green they are. Environmental reasoning is not what motivates me to drive a Prius or commute by bike.

Whether we are behind the wheel or on our bikes, we have the responsibility to safely share the road and be aware of our surroundings. Many pedestrians complain about silent cyclists nearly mowing them down on multiuse trails. While there is some truth to profiling, it ultimately comes down to the individual.
