On a typical work day, the cyclists stream along and do take charge:

Sp far, I only know of 2-3 bike route segments in our area (which means I don't know regular daily bike commuter traffic volume patterns in other areas) and only for short duration of 1-2 hrs. long, where there is significant continuous stream of cyclists commuting, that no pedestrian would want to step in the way.
