Just thought of another one I do. I drive on a very, very busy one lane road on the way home, so people on the side streets always have a hard time turning left because the direction I am going is always packed, even if the other direction is not. As I am driving I specifically look for people waiting to turn and I will stop and let them go. Sometimes I let 5-6 different people go (in different spots along the road) in one drive! I know it may tick off the guy behind me, but I feel like if I do it for one person, they may then go and do it for someone else if they are driving on a busy road.
