Just because they don't injure or kill somebody doesn't mean they aren't a risk. And a number of them come a cropper themselves.Oh, this again. Maybe all those injured by cyclists are in those secret hospitals and morgues I don't know about.
Just because there aren't statistics to back it up, you can't pretend it isn't happening.
Some cyclists jump red lights, then the person coming in the opposite direction is forced to take evasive or protective action.
Some people on bikes hop on and off the pavement causing motorists and cyclists to swerve or brake.
Some ride down the pavement at a right of knotts making you leap out of the way to safety.
If those instances were my only experience of cyclists I'd be inclined to mutter "bloody cyclists putting others at risk all the time" too.
