I actually saw two bicyclist stop for a red light yesterday. It's such an unusual sight, I almost hit the car in front of me.
There is an intersection just below the house, one road is flat and very popular with cyclist, as there is very little traffic, and it's a nice ride on the side of the mountain. That road has the stop signs, and the other road which goes up the mountain is steep, but no stop signs. I've seen and heard many cyclists yell at cars which had the right of way to a bicycle, when the bicyclist ran the stop sign.
