Oh another one that totally pisses me off. You know that center turning lane? You are sitting in it, waiting to turn left and some idiot that is coming towards you stops, thinking they are being considerate to allow you to turn in front of them. They are breaking the law, by stopping traffic unnecessarily. This is illegal, and if you do it to be polite, QUIT IT! If you do that, and someone rears ends you, they get the ticket even though you are the moron.
@cak, to handle tailgaters, simply tap your brakes occasionally. The smart ones will back off, the stupid ones will hit you and lose their license and insurance for being stupid. They also get to buy you a new car.
