Does something have to be fatal before it's worth doing something about? Serious injury doesn't count?
Don't get me wrong, all of it counts and is sad and regrettable. I do however think there is an anti-cyclist bias ingrained in the perception and reporting of it's dangers, that's out of whack with the real numbers on accidents.

But here's the rub - people don't want to put up with even a 1-in-1000 chance of getting a broken arm just from walking on the sidewalk, and they don't want to constantly be on guard against bikes zipping all over the place on what should be a relaxing walk.
It's annoying, and that's why we have things like noise ordnances even though no one ever like, dies because the neighbors are too loud.
