Revealing mistake: 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 mistake: 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).
Continuity mistake: During Comtron's Demolition Derby, Michael engages auto control. Michael controls the wheel during the ski mode stunt. When the car drops back on four wheels, Michael is driving with a regular steering wheel instead of KITT's steering wheel.Joseph Z
Revealing mistake: Across the whole show you see the interior of KITT as being futuristic and curved towards the driver. Also you notice the steering wheel isn't a circular wheel, but a futuristic 'half wheel' with handles. But when you see shoots from a distance you see stunt men driving the car, you can see a normal steering wheel and a normal dash.pierpp
Revealing mistake: 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.pierpp
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.
Revealing mistake: During the Comtron Demolition Derby after Buddy sprays oil, Michael asks him not to push another button. Buddy decides to push the next button for Smoke Screen. The license plate is mirrored THGINK (instead of KNIGHT) before the smoke blows.Joseph Z
Revealing mistake: During the demolition derby, the shot of KITT releasing his smoke screen is flipped; you can see that the license plate is backwards.
Plot hole: At the end of the episode, KITT has to travel about 45 miles in under 8 minutes. That means KITT would have to travel a little under 360 mph for the entire time. KITT couldn't travel that fast until season 4 when he got Super Pursuit Mode, and we never see the speedometer read that high even once.
