Yeah, I was waiting for the Rage Rover driver to swerve and send those bikes into the median divider when they were following him.
Motorcycle vs. car, let alone a big SUV, is beyond a stupid challenge. They only were aggressive because they expected the SUV driver to not hit them (I.E. not break the law, abide by the social contract of non-violence, when they themselves are already breaking it. They expect to get away with the agressive law-breaking behavior only on the assumption their targets are such good mannered law-abiding citizens that the target won't use the same tactics in self-defense.) I'm happy this guy called their bluff.
Also, I feel no sympathy for dipshits that stand in front a vehicle as a means to halt it, and then get their dumbass self ran over.
