There's nothing more irritating than to have someone tailgate me. I'll tell you a story about something that happened just yesterday. It happened when I was coming home from work. I got off the train, got in the car and drove off. Well, I got on the freeway and got my car up to speed. At some point I decided to pass the car in front of me, so I pulled into the left hand lane. I had been in this lane for a few minutes when this car comes speeding up behind me and flashes his lights to get me to pull over. After taking a few seconds to determin he wasn't a police officer, regular or unmarked, I decided to slow down to the speed of the car beside me...and stayed like that for quite a while. Well, needless to say that really irritated him. He was right on my tail the whole time. Eventually I decided that he had had enough and sped up and into the right hand lane. He then pulled up beside me and...

(not the correct finger, but I think the point gets across). I waved at him and he sped off.
