During the race scene, one of the shots is shown reversed to attempt to show the race from a different angle. During one scene the driver is on the right side of the car!
When Daddy-O is being chased by the police he is wearing a striped shirt. When he comes to the truck ramp before the big jump, it changes to a solid-color collared shirt. When the car lands, it changes back to the striped shirt.
As Daddy-O confronts Jana in the beginning after their run-in on the highway, the younger highway worker's tool handle switches between resting on his left shoulder to his right and then back again.
Daddy-O's lips clearly do not match the lyrics he's supposed to be singing in any of the songs he sings.
