Weapons and "crazy" don't play well together on the road. In fact, road-raging drivers in South Africa get so riled up that one pulls out a giant hunting knife and stabs the rear window of the guy recording! From there it gets even worse as Mr. Knife realizes he's driving the biggest weapon of all.
We're just thankful neither was packing heat like this Russian barfly. When a bus almost drives away with his friend's foot stuck in the door, our pistol-packing baddie flips out!
