If you really want the satisfaction of revenge and don't want to escalate the situation to a physical confrontation, you could play the psychological warfare card. I once had a d*uche-bag driver in another vehicle (yes a pick up truck) try to run me off the road (I was also in my car at the time) because he was determined not to let me merge into his lane from an on-ramp. He sped up just to keep me from getting out in front of him, then when I tried to slow down to let him pass and get in behind him he slammed on his brakes and literally ran me into the shoulder nearly putting me into the wall... going 60mph on the highway.

I took down his license plate number and had a friend in the police force run his plates to get me his home address. I then went to a local news stand and grabbed the subscription cards from about 50 different magazines, ranging from sports illustrated to better homes and gardens, to the most vile and disgusting porn mags of every possible variety you could imagine (and believe me there is some sick sh*t out there). I then filled out the cards and checked the "bill me later" box at the bottom. I mailed them in and slept well at night knowing I was about to make this guy's life a living hell. If you ever tried to unsubscribe to a magazine before, it's a real PITA. Try doing that with about 50 mags at the same time, as well as explaining to your wife and kids why you have a subscription to "Horse-C*ck Lovers" magazine.

I was going to eventually send him an anonymous follow up letter saying how I hope he enjoys reading, and to think about it next time he deliberately tries to kill another motorist. But I never bothered because I decided he wasn't worth the postage stamp.

It was the most fun I ever had committing federal mail fraud.
