As someone who lives in a big university towns in which there are bike lanes on the roads, independent of sidewalks AND roads, I say:
Bikes belong on the roads. Bikers need to not be cockbags, and drivers need to slow the fuck down. The kids on the bikes annoy me too, sometimes, but they annoy me way more when I'm trying to walk on the sidewalk than when I'm driving in my car.
Way more. Indescribable amounts more. Plus, there are laws for them on the road.
I didn't watch any of the videos (because Glenn Beck is a ridiculous psychopath who should be put down) or read anything, but mostly this is an argument about individuals, not bikes on roads v. sidewalks.
