I too have a bit of a problem while driving. What makes me tap my nails is waiting in line while trying to get out of a shopping parking lot, although I do occasionally see a bit of humor. The morning after Thanksgiving at the Wal-Mart sale, I am waiting for the cop to release our lane, these two little elderly ladies from a near by town pull into the lot, turn down the wrong entrance to park, with three cars coming toward her. The guy she meets head on first is shaking his fist and waving to GO BACK!! She just inches on up closer and waves as if he just MIGHT be making a move on her. This continues for the three minutes I am sitting there. By the time I got to the main entrance, I was feeling sorry for her, mad at the guy, and ready to run over the cop!!!!
