Roscoe is only following a few yards behind the Lulu-driven General Lee, yet in the "viewed from the rear" shot of Roscoe's patrol car landing after the jump, there is no visible General --- or even any residual "hanging in the air" dust from the landing --- visible further down the road in front of the spot where Roscoe lands.
Roscoe plows his cruiser into a dense thicket of tall-stalked shrubbery and makes the hood unlatch and fly up, yet when Roscoe gets out to close the hood again, there is no visible vegetation-mound in front of his bumper.
The same location is used for both scenes where the Dukes and Roscoe both make a jump during a period where Roscoe is pursuing the General.
When leaving the Boar's Nest to stay with the Dukes, Lulu walks up to the General Lee. Luckily, the camera pans away to the kidnappers nearby, since the doors to General Lee are welded shut and the overweight Lulu would not be able to get in the car without having two other people's bodily lift her up and squeeze her in through the window.
