Roscoe and Cletus are both driving Plymouth Fury patrol cars while chasing the Dukes, yet when Cletus slams into a tree, the car is an AMC Matador.
While Roscoe and Hogg are first struggling with the inner-tube around their necks, the door of the garage is closed and swinging slightly as if Bo and Luke had just then gone out. Yet an instant later, the Dukes are seen emerging through the partly-open door into the street.
The single-vehicle-wide bridge appears to just be a fake "prop bridge", as there is not any visible stream or gully for it to span; it's evidently just built across a flat grassy field. The two Hazzard County P.D. cars don't even fall over an embankment or any kind of dip in the terrain; they merely skid around and come to a stop in the dry level field.
The General starts to move before the sound of cranking and revving of the motor is heard.
J.D. never looks to his right as he and Roscoe are ambling back to the stolen-goods warehouse, so he could not have noticed Jesse sitting on the park bench.
