Never mind cycling etiquette, what staggers me is the almost complete lack of visibility most cyclists I come across have when it's dark. Look, bud, riding a black bike, while dressed all in black with only a tiny red light (if at all) does not make it easy for me to avoid running my half ton of steel over you. Try, oh I don't know, a reflective strip, or better yet, wear a color that actually doesn't camouflage you with the buildings! I'm just sayin'...
