Recently a motorist in Santa Clara county (south of San francisco...think silicon valley) got 3 years for hit and run on a pair of cyclists, one was seriously injured, the other less seriously injured.
The convicted motorist: was driving without a license, had prior dui issues, hit and run, actively tried to cover up the accident (tried to ship car out of state, get repairs done off the books).
So it appears circumstances make the difference and drivers do get charged and convicted. I would expect the same when a cyclist hits a person, circumstances make the difference.
I think that if we saw all of the stats though, there is probably an astoundingly low percentage of collisions where the at fault person is charged whether it is car hitting car, pedestrian, cyclist or cyclist hitting car or pedestiran, or pedestrian doing stupid things causing an accident.
