Revealing: When KITT takes part in the race and goes up on two wheels, you can see that the stunt driver is behind the wheel and that a dummy is strapped into the passenger's seat.

Continuity: If you look closely at KITT throughout the pilot, the position of his scanner lens changes from being the normal scanner that we're all used to, and the scanner being at the very tip of the front bumper. (The latter case is because the car was used for a promo shots to sell to NBC, and after the show was picked up, they changed KITT's look, but still used the earlier shots).

Other: During the demolition derby, the shot of KITT releasing his smoke screen is flipped; you can see that the license plate is backwards.

Revealing: There is a scene where KITT drives over to Michael, and you can see the drivers seat is really a guy dressed up in a light brown suit to look like a car seat. You can see for a visor that its a glass panel made to look like a hollow head rest, but you plainly see the guy take away his hand off the steering wheel.

Deliberate "mistake": Watch the scene when Michael fell asleep. At the end of the cop chase the cops get out. Watch the license plate California KNIGHT in yellow letters. The next scene reads Nevada MCC224 and has an original Trans Am rather than KITT's rear.
