There is often this friction between car drivers who occasionally bicycle and bicyclists who don't bicycle in the manner they do. When driving a car they are often the ones shouting "get on the sidewalk" etc. because that is where they would be riding their bicycle. What is really sad is these people are often the most aggressive in their behavior towards bicyclists. If waiting "several minutes" to safely pass someone on a bicycle is a source of irritation for you then you should really ask yourself what your priorities are in life are. It's time to see a therapist. What I find strange is that with all the extra endorphins cyclists supposedly get from cycling why are so many of them angry much of the time?
