One time I was driving carefully on a twisting mountain road. (Bear Creek Road, for those familiar with California's Santa Cruz mountains.) A little sports car sped up behind me, tailgated for a bit, and then swerved around me an sped off down the road. A few miles later, I came across him standing at the side of the road, his steaming sports car wrapped around a tree. I confess I felt schadenfreude, big time!
