Factual error: In the shot of the infield at the Saratoga racetrack several Canada geese are shown landing. However, the calls inserted on the soundtrack are the quacks of mallard ducks not the honks of Canada geese.
Factual error: At the beginning of the movie when all the guys are in the barber shop, a man is wearing a John Deere hat with the modern logo, not the one from 1976.
Other mistake: For the entire length of the movie, Bam Magera is referred to as Bam. But in the credits, his character's listed as Chad.
Factual error: All UK driving test instructors must wear a yellow reflective waistcoat or jacket while instructing someone during their driving test. This was still true in 2002 when the film was shot.
Revealing mistake: When Lex gets out of the shower after his last training session, you can see his black briefs when he towel dries himself.
Continuity mistake: When Kurt and Markie are racing together in the Ice Leg, if you look closely at the part when Markie is about to crash into chunks of ice, Kurt's car has no graphics, and a lighter green windscreen.
