Continuity mistake: A truck with load pins loaded with PVC pipe bypasses the weigh station. After Ponch and Jon pull it over, the truck driver gets out of the truck and the load pins are gone. (00:17:10 - 00:20:20)
Revealing mistake: A load of PVC pipe is secured to the truck with three straps. When the driver yanks on the rear strap, which comes off easily, the other two straps automatically become disengaged allowing the load to fall off the truck. (00:20:20)
Other mistake: As corvette guy races to get away from Ponch, the steering wheel breaks away, coming loose in his grip. Yet the car magically veers a sharp left before halting to a stop, instead crashing into the trees straight ahead of him.
