No one can say what started all this before the video started rolling, but from what I saw, you have some bikers that were too set on revenge to use common since. If I had been in the SUV, there would have been more bodies scattered down the freeway. There is no reason to attempt to take out a full size vehicle on a bike. If you do, you should atleast have a hand gun. Even if that is the case, I would bet on the SUV. As stated before, don't know what the cager did, but from the video, the bikers were real tools, and clearly at fault. I would have run them down like a snake in the street (I would have said stray dog, but I like dogs, but no one would miss a snake).
