Factual error: Realistically, there is no way someone can be thrown straight up from the driver's seat of a Pontiac Trans-Am, even with T-tops. Whoever was being shot straight up would probably break their legs on the crossbar that's adjacent to the windshield.
Factual error: A secret file is password-protected on a computer, requiring a six-digit numerical access code. KITT states that the possibilities "are virtually unlimited." In truth, if each digit can be 0 through 9 (numerical meaning no letters or symbols), the possibility is 1 in 10^6, or 1 in a million. A supercomputer like KITT should have no problem running each number systematically until a correct code is found.

Factual error: The scenes outside the motel in Calexico show a large mountain range in the background. Calexico is actually located at or slightly below sea level. The only mountain in the vicinity is Signal Mountain, which is an individual mountain, not a range. (00:24:30)
Answer: I would say that unless there's visual evidence it was another K.I.T.T. car, as in you could see the bar scanner or cut steering wheel, people on here would correct the mistake by saying more than one 1982 Pontiac Firebird Trans-Am was sold and there's no reason it's meant to be a random car.
