I always find it funny when drivers (myself included) use the turn signal when the turn signal is totally unnecessary. For instance, there is a street in the neighborhood that makes a 90° turn to the right, but is not an intersection, and I find myself using my blinker sometimes. Just this morning, someone in the parking garage used their blinker to indicate that they were going to go up the ramp, which was the only possible direction for him/her to go. Totally unnecessary. (Yes, I got nothing much to write about today! :))
