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.
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!
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.
