Most road rage is just speeding until some jerk decides to “teach the speeder a lesson”.
The Camaro driver is an idiot (mostly for owning a Camaro), but the pickup driver is the punk who turned a brief encounter into a minutes-long battle that caused the idiot to get really stupid.
I’ve had this happen to me going north to Chicago on I-55. Some Arab looking guy in a fancy sports car was trying to wedge in like the Camaro. When he realized he couldn’t do it, he started the same tailgating. I was stuck with truck on my right and the shoulder to my left. The guy behind me kept tailgating like mad...before I could speed up and pass the truck, the guy behind me swerves to the left and comes up the shoulder fast with very little clearance. If you watch the video here, when the Camaro does this, the pickup looks like he speeded up also...He should have slowed down and let the Camaro pass, which is what I did.
