Tailgating is an annoyance caused by aggressive drivers.
I’ve found some of the best examples of tailgaters receiving immediate karma for hanging on someone’s rear.
This redneck in a lifted pickup tailgates a woman for a few minutes before swerving to the right of her and around, while flipping her the bird, before speeding ahead, losing control and careening into a ditch. You can even watch a news segment cover it.
