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
Continuity mistake: As Michael realises how he will be stopped on the way to the airport, he pulls over. KITT's front lower bumper does not have its spotlights, it is just a plain bumper.
Continuity mistake: After Michael gets shot and gets in his car to race to the airport, he calls Devon on the intercom. Before he gets into the car, he flinches and grasps his left side shoulder area where he was originally shot. When he talks to Devon, he's grasping his right shoulder. After he finishes talking and continuing the drive, he grasps the left one again.Joseph Z
Continuity mistake: When KITT first stops talking the Auto Normal and Pursuit mode indicators change from old fashioned very angular with a different font and switches to the newer rounded rectangle with then new font. It does this several times.Benjamin Lesley
Continuity mistake: The crooks steal KITT. When KITT announces himself, the crooks slam on the brakes. When the car comes to a halt, the back seat cushion is thrown forward. When the crooks take off, the back seat looks as if it hasn't ever moved forward.Joseph Z
Continuity mistake: When KITT drives off the edge of the cliff, the car changes from a pontiac to another standard car a number of times. When KITT lands, his flight trajectory was from approximately 10 feet, not 100 feet. He should have landed like a belly flop onto the sand, not a shallow dive.
Continuity mistake: When the police helicopter sees dead Michael by the car, he turns 180º around between shots.Sacha
Continuity mistake: When Michael is racing to the airfield to stop the bad guys, when you see inside the car it is clear and sunny outside. Next shot of outside with the car skidding the driver is wearing a different costume, possibly taken from another episode. Then the outside is foggy, back to clear, then foggy as he approaches the jump. (00:39:15)martin79uk
