Being a bicyclist or pedestrian isn't a religion. We aren't required to stay out of cars in order to get into heaven. We're not in a club that will ban us for using a motorized vehicle. Machka's got it right. It's just life. All of us seek happiness in our own way. Stay on the bicycle or on foot if that makes you the happiest. If you need a car sometimes don't get mad at yourself. Just use one. They're tools.
