Other mistake: When Wrangler is first seen, he is shown autographing tickets by driving over them. There is a tyre mark shown on the tickets when he first does it, but a few minutes later, when he autographs Cruise's tickets, there's no tyre mark on the tickets, even though he used the same method. Also, when Lugnut shows the tickets to the police car at the end, the tyre marks have now appeared. (00:08:05 - 00:11:15)
Other mistake: Wrangler is talking with four of his fans, and one of them puts their ticket on the ground for Wrangler to drive over it and leave a tyre mark on it. The tyre mark left on the ticket does not match the angle at which Wrangler drove over it. (00:08:10)
Other mistake: Wrangler is seen training for the race by driving around a race track. In the first shot, he is driving around a corner, then he is driving through the track. He is then on a television being watched by Coupe, and the lap time is being recorded. However, the timer is shown just starting at zero seconds, even though he should be midway through the lap by this point. (00:11:35)
Other mistake: Coupe is watching Wrangler train for the race through the television that is shown displaying an overview angle of Wrangler, and sometimes a side angle of Wrangler. However, for this to be possible, there would have to be a camera filming this and there is no camera is ever seen filming Wrangler. Especially in the angles that were shown filming him. (00:11:35)
Other mistake: Wrangler knocks over a canister of oil which starts spilling oil onto the ground. There is a hole visible on the canister where the oil should be spilling out of, but no oil is shown spilling out of the hole. It is just shown spilling across the ground on its own. (00:20:35)
Other mistake: The canister that Wrangler knocks over when he taints the Champ's fuel supply starts spilling oil onto the ground. A puddle can be seen being made from the spilt oil and is shown spreading across the ground just before the scene ends. When the oil puddle is found the next day, it is virtually the exact same size as it was the previous night when the scene ended, even though the puddle was in the middle of spreading across the ground.
