If you have not see the NYC Biker Rally Vs Range Rover here is the video
Bikers claim the Ranger Rover bumped one of the bikes and so the Bikes stopped and surrounded the Range Rover and Started going to town on it. The Driver says he was in Fear of His wife and child life so he ended up running over one of the bikes and bikers,(the biker that got ran over is in pretty bad shape) This can be seen in about the 37 second part of the video. The rest of the video is the bikers chasing down the range rover.
They catch up with him in stopped traffic and break his windows and haul him out of the car and lump him up pretty good. The driver of the Range Rover has not been charged with anything.
Turns out there was a undercover cop that took part in the rally and also in beating down the Range Rover. He has been arrested and charged.
