This post brings several things to mind. First motorist think that the roads belong to them. In fact it was cyclist around the turn of the last century that demanded and got good roads. Therefore cyclist could make the claim that motorist are using our roads.

Most laws allow bicycles to use most any road or hiway as well as cars.

As far as sidewalks are conserned, here in Lincoln I see some cyclist using a major street during rush hour when there is a very good hard surface bike trail running next to it. And yes the cyclist may have to slow down for walkers, but it is no different than cars having to slow down for cyclist. Especially during rush hour I suggest the cyclist use some common sense and ride the bike path. Riding in traffic during rush hour slowing down traffic only gives motorist even more reason to hate cyclist.
