Yowwwwza!!! Seems like it was a party atmosphere, with all the different cameras. Somebody wasn't paying attention to their driving.
A similar event occurred to one of my motorcycle buddies two weeks ago. He was in a group of four sport bikes on a two lane highway. They pulled out to pass two cars, the second car eratically pulled out in front of them and caused a chain reaction where the bikes hit the back of the car. 3 bikes down, but fortunately only cuts and bruises.
The irony is that my buddy had sold his bike, they were going to look at a new bike for him, and he was on a borrowed bike. So one guy owned TWO bikes in the crash.
