The biker who shot the helmet-cam video said he started taping after seeing a water bottle fly out of the sunroof of the SUV.
Obviously, he cant show that on the video since the cam was turned on after the bottle was thrown from the SUV. But if thats true, that might explain the agressive demeanor of the bikers. Certainly, it doesnt excuse it, but might provide a clue as to [DEL]how[/DEL] why the whole confrontation began.
Its a little bit suspect that the "battery cut out" on the helmet-cam just prior to the SUV driver's beating.
I just thought he had a very brief moment of clarity long enough to realize he should turn off the cam. Didn't know his story was the battery died. Not so sure I buy it. At any rate I completely fail to see how a water bottle could get someone to that level of anger. If that's the type of handle those guys had on their emotions, they shouldn't be operating a vehicle on a public road.
