Worst case of road rage I've seen.

When I lived in Australia, I was driving on the freeway and a guy behind me slowed down, stopped and then the passenger jumped out and kicked the door of the car behind him in while the rest of us were doing 60mph. Then they sped off, really sped off and 4 wheel drifted round the corner of the offramp. Weirdest thing I ever saw there. And on a weekday!
