Good story. I used to be a car-hitter. I stopped after reading too many road rage incidents.
I did follow a guy to his house one time last year (he ran a stop sign and almost hit me) and have a conversation with him when he got out of his car. I was calmer by time I had followed him a couple of blocks, so it was (I hope) a more productive conversation than if I had yelled at him at the time.
