This is one of my pet peeves from my pet peeve zoo.
1) People who walk/run/ride/seg on the wrong side where they can see that everyone else in their lane is going in the opposite direction
2) Chatting to others or on phones totally oblivious to traffic
3) Stopping/standing/ to socialize in the bike path
4) People who allow their children to play/sit/lie down in the bike path
