On rare occasion, if I'm in a double turn lane and am on the inside lane at an intersection and the driver next to me isn't paying attention, I'll flick the wheel just quick enough and short enough to upset the balance of the car...sort of a corner check move.
I saw Button do it to Coulthard in an F1 race once and it spooked Couthard just enough for a split second that he backed off and held his lane
Another personal fav is to wait for the tailgater to bring the hot coffee up to their mouth, and then DYNO that brakes for a half second. Totally stupid thing to do but oh so gratifiying when you can get them to dump it in their lap.
