On my shared straight/right turn lane where I go straight, when the green arrow appears and I'm first in line with a car with no turn signal behind me; I 've just started pointing at them and then pointing right as if to say, "YOU, RIGHT-TURNER, GO!" So many people fail to use their turn signal, yet still get pissed when I'm in the lane, that I have to be traffic cop up there. I'm biased left but still most motorists are still stopping behind me, which is fine, I just need to play traffic cop. Better that than get run over.
