Well, a bicycle plus rider is about 100kg, which is a tenth of an old-fashioned car or closer to a twentieth of a SUV, so that should correspond roughly to getting hit by a car at about 1MPH. I'm not awfully worried about cars moving at 1MPH, and correspondingly unworried about bicycles. You may disagree. Do you happen to drive a car? At 1MPH, or faster?
