Once, when I was driving home late at night, a Landcruiser came up behind me flashing its lights and wanting me to switch lanes so he could keep going insanely fast in the left lane -- as they do. This time I decided not to switch lanes; I was turning left at the next roundabout, and since I was going over the speed limit anyway it's not like the other driver could legitimately be upset I was slowing him down.

The Landcruiser driver swerved dangerously around me, cut me off, and then slammed on his brakes and brought his car to a halt. I, of course, had to come to a stop right behind him. He leapt out of his car and started towards my car, shouting. Then he caught sight of me, blanched, turned around, got back in his car and drove off.

I've sort of been assuming that he thought better of coming to intimidate a single female. But maybe I'm just really scary-looking? It's a mystery.
