when I'm a pedestrian, I get angry at cyclists because the zip past me on the sidewalk going 10-20 miles an hour. what happens when you run into someone at that speed? why don't you think about other people? when I'm a motorist, I get angry at cyclists when they put me in danger. driving at night on country roads can be tricky, and sitting behind a cyclist who is going 8-10mph on a 45mph road puts me in danger to other cars who could rear-end me. why do I have to put myself in this danger for your hobby?
