I give waves of thank you, and sometimes the "I ****ed up, i'm sorry" wave There is no need to abuse other drivers on the road, the real tossers will hopefully kill themselves off, with any luck they might take some other tossers with them, unfortunatly instead they generally survive and kill the few good people around. any way back on topic, the only other signal I give is hazards on and a quick swerve from side to side after overtaking the car doing 30 or so below the speed limit that keeps speeding up every time a good spot to overtake comes around. It's like saying F**K you but its fun to watch.
