In my 3 years of commuting so far I have only a few incidents where drivers shouted something at me. This one time I was still in the bike lane (which are all over the place in my area, which are just the shoulders of the road really) waiting to make a left hand tunr to get across the street. The road was only 2 lane (no middle or I would have waited there for the turn). As I was waiting by looking both ways this guy passing by shouted "make sure your looking behind you" which just confused me as I was already doing that.
Others that seem to be the most popular are people that honk as they pass by, which have happened two times recently: 1) When I was waiting at a crosswalk for the light to change 2) the other was when I was riding down the sidewalk. Both of these were perfectly fine, I dont do stupid acts or anything to warrant these... idk its weird.
