You're unlikely to report every time a bike runs into you. Most of the time you won't even be really injured - just some bruises and pain. That's not big enough for statistics, but it still sucks as an experience.
My guess is that's the same for cars (minor injuries go unreported). It's hard to speculate about unreported statistics. The fact remains that for reported statistics, motorists injure far more people than cyclists, thus I say fear of cyclists is irrational.
