Since I have been driving the speed limit, I have noticed that I have been tailgated quite a bit. I can't blame them as I have done my share of tailgating of slower drivers in the past. I try not to tailgate now (although if anyone is driving slower than I am, they are almost certainly below the speed limit). Today, one jerk in a BMW tailgated me half of my drive to work. This wasn't so bad as I have gotten used to it, but it spent most of the time with his middle finger pointed in my direction.
With most tailgaters, I keep myself calm by singing to myself some impromptu song about tailgating, such as Monty Python's song Sit on my Face with the word "face" changed to "butt."
