Nope, never done that.I'm sure we've all done it. I've done it too, that's how I know it's stupid. The faster we are going, the less physics is on our side.
The last bit of road rage that I've had the pleasure to be involved with was just over 2 years ago.
On my way home after a night shift on a particularly icy morning I was cut up by a brand new Mercedes, so I laid on my horn.
The driver kindly showed me his middle finger shortly before slamming on his brakes, I just managed to miss him.
He thought I'd be a jolly jape to try it again, this time I pulled up alongside the back of the car, and brought my fist down on his boot lid as hard as I could, making a sizeable dent.
He drove off, and haven't seen him since.
