You know what happens when a cyclist is involved in a traffic accident they cause? They might get hurt or cause some minor property damage. When the driver of a car is at fault they kill other people, so I'm not too worried about even negligent bike riders causing an accident.
As a pedestrian I find your analysis a bit myopic... but on par for far too many cyclists.
We recently had a funeral for people killed in an accident that was not caused by the car driver. When cars and bikes share the same space, it might be an impact with a car that kills somebody, but that impact might be the result of a chain of actions initiated by a bicyclist.
