Revealing mistake: When Lightning McQueen is being shown the simulator in the plant, the times shown on the simulator don't work. A regular timer would say, for example, 21.99 seconds, but the timer on the simulator screen only goes up to 21.27 seconds, if you watch it. I assume this is because of the Frame Per Second of the movie, and wasn't noticed, being as most cartoons etc run at 25-30 FPS.
