Well actually, its usually much safer for a cyclists to keep moving at an intersection like that. It takes far less time for them to clear the intersection than coming to a full dead stop and starting again. I can see and hear everything on approach much better than anyone inside a 2 ton metal box. In some places its perfectly legal for a bicycle to treat stop sighs like a give way.
Getting on the sidewalk often has its own hazards, like the sidewalk randomly ending and starting again for no reason, people, and shop doors.
