Kinda. The first biker cut off the Rover and slammed on his brakes. He got bumped, and then the Range Rover driver got swarmed by the pack with his wife and daughter in the car. They busted out the windows, slashed the tires, chased him for a while and then dragged him from the car and beat the **** out of him. We can't see what the guy in the SUV did to provoke them, but given how rational groups of those people are it probably wasn't much. This wasn't the first time they've pulled **** like this.
