... to a guy who commutes regularly at night. We cross paths frequently (I take the car in the evenings to pick up my mom from a nursing home), and this winter it freaked me out to see him on the road only until I was about 10 meters behind him. Old, beat-up bike, no reflectors, regular/dark-ish clothing.
I know a reflective vest is probably not enough (but it has LEDs!), but I hope this keeps the guy from getting killed.
