Truck was going slow..."maybe" had some mechanical problems, biker got pissed off because of slow truck, truck notices biker is pissed and doesn't give a fuck, biker passes and flips of trucker, trucker becomes enraged and starts driving erratically with biker in front...wait, what happened to the truck that was having mechanical issues..., biker brake checks truck(that's brilliant), truck goes around biker and brake checks back(remember bike was behind truck at the off ramp), both are pissed, both are not going to back down, biker feels like his life is in danger, shoots at truck numerous times(idiot), trucker freaks out and pulls in Autozone so he can fix his truck and escape, biker doesn't give a fuck...pulls into Autozone too and tries to kill trucker...only stopping after he thought he landed a head shot, end of story...except for what will transpire in court. That's what happened!
