The jogger thing annoys the hell out of me; I don't mind most of them...the majority just hop back into the sidewalk when someone is coming...but the ones who stake out a piece of street/bike path, wearing headphones while aggressively forcing road/path users to react to them are one more notch on the inconsiderate annoyance list.

I don't get the peds in the street thing either...I was driving on a relatively fast two lane road the other day with a guy just walking in the middle of the left lane, against traffic. That was drugs/alcohol.
