How did you come up with that stat for "car crashes"? Does it derive only from ER data? Are you including "car crashes" that do not involve any trip to the ER or morgue trip for the car occupants, where they walk away uninjured?
I doubt that the percentage of all cyclists involved in a "crash" with a car and don't take a ER/morgue trip afterwards is anywhere near as low as that for the occupants of vehicles involved in all auto crashes.
