On my way home after an evening class last night, I came up behind another cyclist. First thing I noticed was though he didn't have rear blinkie or front light, he had a flashlight hanging from a zipper or something. It was surprisingly effective.

Second thing I noticed was he stopped at every stop sign, even the one at the pedestrian crossing that I sometimes blow through (if there are no peds). He rode on the street, not the sidewalk.

No helmet. So I'm puzzled. I don't think he took the Road I course, or he'd have gotten proper lights and would have been wearing a helmet. But he knew enough to ride on the street and stop at stop signs.
