Knight Rider [Pilot; a.k.a. Knight of the Phoenix] (1) - S1-E1
Other mistake: After KITT takes over after the hoods steal him, in the big intersection, when KITT's doing donuts, it's a stunt car and driver, as the steering yoke is a regular round wheel.
Other mistake: When the woman plays the video to show the people K.I.T.T, most of the footage you see cannot exist, especially seeing Michael driving inside K.I.T.T on K.I.T.T's monitor. Also when K.I.T.T crashed through the Comtron door from the pilot later on - when Michael sees the footage, this is just footage from other episodes rather than surveillance footage. (00:13:25)
Knight Rider [Pilot; a.k.a. Knight of the Phoenix] (1) - S1-E1
Other mistake: As Michael is driving to Millston, he asks about a radio. When KITT first asks "What would you like to hear?", the red square that indicates he is speaking doesn't blink until the camera does a close up on it.
Other mistake: In an overhead shot of KITT speeding through the desert after Lauren's plane, you can see parts of KITT's hood wobbling against the wind. I seriously doubt a car made to be indestructible would have that happen.
Just My Bill - S1-E6
Other mistake: Just as Michael jumps over the roadblock, the whole front of K.I.T.T. flexes showing it's not a real Trans-Am but a mock up.
Other mistake: When Michael is carrying Micki up the cliff, she's supposed to be unconscious. But he's not holding on to her and her hand stays wrapped around his neck to hold on. Not something she should be able to do. When they're near the top, her hand position changes, but she's still able to hold onto him.
No Big Thing - S1-E8
Other mistake: When the semi is approaching Michael head on, KITT tell Michael to hit the brake, which Michael does. Then KITT tells Michael to put it in reverse, which Michael does. But then KITT says "why reverse, we could have jumped over?" as if he wasn't the one who suggested reversing.
Other mistake: When the guy goes to go around KITT to get behind Michael, as KITT cranks up, you see movement in the front seat.
White Bird - S1-E19
Other mistake: As the guy is shooting at KITT at the retreat, the sparks of the bullets run down the passenger side toward the oak tree with the blue and white umbrella on the patio. Even though Stevie is a blond wearing a blue sweater, the profile and arm appears to be Michael. A moment later, same thing down the driver side, with Michael's arm and profile.
Knight Rider [Pilot; a.k.a. Knight of the Phoenix] (2) - S1-E2
Other mistake: When shooting at KITT from the helicopter, the shot ricochets and hits the port side of the chopper, but the starboard side has the flames coming out.
Slammin' Sammy's Stunt Show Spectacular - S1-E5
Other mistake: At the end of his "audition", as Michael approaches the pit area, it's his stunt double with a bad wig.
Other mistake: When Michael and Marty are being chased and shot at, K.I.T.T jumps over the top of a hill. In the next shot of K.I.T.T driving away, you see a wheel trim rolling down the hill which has fallen off K.I.T.T. (00:39:45)
Other mistake: As KITT has the guy pinned by the fence, asking questions, the passenger mirror is angled out in an impossible angle so there is no reflection.
No Big Thing - S1-E8
Other mistake: As KITT meets the pickup with the camper, it appears that KITT has no windshield.
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.
