Because like a lot of FReepers here who feel the same I’ve almost been hit by them several times in my car once on the street. Not talking about kids, talking about adults who should know better but don’t or don’t care.
As for kids, don’t even see them on bikes these days they are so glued to those hand held what ever you call those. See a few on skateboards but that’s it. In fact will tell you this, kids who ride skateboards have much more manners than adults who ride bikes!
Oh, okay. You've ALMOST been hit by a person on a bike in your car and therefore all adult bike riders are worth your disdain. Got it.
