Continuity: In the pile-up on the freeway, the same yellow Cadillac hits the pile twice.
Continuity: In the sequence where the girls in the van give the black guy in the Lincoln a spray of the fire extinguisher, the road they are on changes from a two-lane road to a four-lane highway between shots.
Continuity: When Mrs. Schulenberg and her two daughters take a bottle of champagne to Mr. Schulenberg before the race, he is not wearing any glasses. However, when she speaks to him he suddenly is wearing a pair of sunglasses. The sunglasses disappear again at the end of the scene.
