Had something similar happen to me about ten years ago but with much different results. One Sunday our family was headed somewhere so we got on the fwy. A group of bikers, a bunch of younger guys in crotch rockets, entered an on-ramp right by us. A couple of them recklessly cut in front me almost causing me to hit one of them, so I honked, thinking he might not know I was there. One these but threads the moved in front of my car and deliberately slowed down to show me who was in charge. The rest of the heard finally took off after a couple minutes of this little power dance, and the moron finally joined them. I was afraid they were going to do something stupid like try and force me off the road, but fortunately it never reached that point.
I don't celebrate the guy in the RR running over anyone, but I understand why he did and what he was feeling.
