Here's my take and it's only my opinion so it doesn't have much value, if any. However, the way I see it, the guys on the motorcycles were more capable, and better equipped, to end all of this before it started. The guy in the big pickup is less capable of avoiding or escaping the situation. In other words, the truck is slower and less maneuverable than the motorcycles. The truck driver just can't speed away to avoid the motorcycles. The guys on the bikes have much more capability to leave the situation and let it end. They didn't. Frankly, if you ask me, they are lucky the truck driver didn't run right over them. Instead, he pulled over and the guys on the bikes were dumb enough to do the same, even after it was apparent that someone in the truck called for backup. Stupid move.
