Diesel spills on the road (usually on a bend or roundabout when you happen to be pressing on)
HGV drivers who insist on being 12 inches from your rear bumper in traffic
People that drive at 40mph in a 60mph zone and when you go to overtake either speed up (Idiots!) or flash their lights/blast their horn at you like your the one who is doing something wrong
Jehova's witnesses knocking on your door (Sneaky round our way, they have been sending very attractive young ladies round!!)
