I ride my bicycle daily in the city. At least once during each trip, a bicyclist blows past me, on the right, and runs the red light that I'm patiently waiting at. Very often, he or she cycles through a crowded crosswalk or in between cars attempting to cross the intersection. This behavior is what gets people mad. I get mad on the rare occasion when vehicles intentionally try to run me into parked cars. I never understood, other than impatience, why a cyclist would run a red. Preservation of momentum is just a relinquished opportunity for good exercise. Running a red is literally shortening the cyclist's life by depriving him or her from the foregone physical activity.
