People who sit at a light or stop sign waiting for "traffic to clear" B4 they turn. Argh! :| These people will sit there all damn day waiting for a totally clear lane. One turn in particular, right by my main job, you can see down the road for more than 1/2 mile. Totally flat. You can clearly see if anyone is coming, but these people will not move if they see a car waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay down there. It's a good thing I don't have a big diesel dually truck with a 500-pound wrought iron grill guard.....
