I wish adult joggers in US would please wear reflective something when running on street. Few days ago I pissed off a biker and a jogger because I didn't see them in time to stop at a safe distance away from them. Guess what? BOTH were wearing BLACK shirt/shorts. Because they were running from my 10 oclock to 2 oclock (outside of cone of headlights), I just couldn’t see them.
