During the end race, Cole is trying to make a space between the lead car and another green car. When he first tries to squeeze through, the green car is a skoal car. the next time you see the green car, it is a Quaker state car.
Another time during the movie, Cole says something to Harry and the camera shows Coles face but his lips are not moving.
A lot of the time during the movie, the cars are in different orders and or they are closer together or farther apart than they are suppossed to be.
