Whilst driving to work, I was stuck behind a slow moving vehicle on a 60MPH road. So I kept over to the right of the road and at a safe distance from the driver in front. This must have annoyed him as he randomly hits the brakes so hard you can see the front of his car drop. When the road is clear, I safely overtake him and ignore the fingers and swerving into the side of my car.
That's not the end though, because this idiot then decides to undertake me and nearly ends up in the back of the horse box. I've encountered my fair share of morons on the road, but this one has some serious anger management issues.
