Can you point me to the bicycle-pedestrians injuries and deaths per capita versus car-pedestrians injuries and deaths per capita?

Don't have those numbers on hand any more (the former figure is so low that it's almost impossible to find), but per mile traveled within a city, there is no contest that cars are the biggest threat all other things being equal.

What I do have is that 12% of pedestrian injuries are motor vehicle related (3rd leading cause of pedestrian injuries) and that bikes don't even register in the top 6. 3 out of 4 of these accidents were in urban areas. For bicyclists, motor vehicles are the number one cause at 29% of injuries.[0]

I'm pretty sure that if we we doing this the smart way, we'd start with statistics when deciding what rules to create and which ones to enforce. The goal should be minimization of injuries and deaths. Cars majorly fail in this respect.

When a pedestrian gets killed by a cyclist it is news. We rarely even report motor vehicle pedestrian deaths unless it is notable in some way (like the Uber incident). I don't remember who said it, but the definition of news is something that happens so infrequently that it is notable enough to report on. (I think Bruce Schneier but can't find the quote right now)
