My bike route to work takes me on Kifer between Lawrence and Bowers. This is a stretch or road that see quite a few bicycles, probably partly because one can cross over the railroad by Lawrence station. It has two car lanes in each direction where the cars can get pretty good speed. (Think the speed limit is 40 mph.) When bicycles bike along the side of the road, it is really not a whole lot of space to fit also car in that rightmost lane. At the same time, the traffic intensity on this road is not nearly high enough to warrant having two lanes in each direction. Also, no cars are ever parked along this road. The cars all park in the company parking lots. Seems one really should create bike lanes and keep only one car lane in each direction. Note that this stretch is marked with 'Extreme Caution' on the Santa Clara Valley Bikeways Map.
