Just My Bill - S1-E6
Continuity mistake: The blue car is chasing KITT out onto a public road with striping. In one shot from the blue car, they're on the private road, then suddenly back on the public road.
Continuity mistake: To elude KITT, KARR ejected Tony to eliminate weight. A moment later, KARR is sitting still, and Tony is in the passenger seat.
No Big Thing - S1-E8
Continuity mistake: When Michael and KITT stop at the gas station, the driver's front tire goes from normal to slack and back again.
Nobody Does It Better - S1-E21
Continuity mistake: When Michael gets hit on the head in the private investigator's home, he falls in the chair and faces left. Next shot of him he is facing right. (00:17:45)
Nobody Does It Better - S1-E21
Continuity mistake: When Julian leaves the building during the party, you can see this isn't the actor playing the role of Julian but someone else. (00:23:10)
Nobody Does It Better - S1-E21
Continuity mistake: When KITT forces the 4x4 off the road, you can see both people inside when it crashes wearing their safety harness. In the scene before when you see inside none of them are wearing any kind of belt. (00:37:40 - 00:38:15)
White Bird - S1-E19
Continuity mistake: When Michael and Stevie are in the car and it jumps through the panel on the trailer, when the car lands and it cuts back to Michael there is no trailer in the background. (00:17:05)
White Bird - S1-E19
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)
Continuity mistake: When Michael is in K.I.T.T and he is taking the professor's blood pressure, the boot is open. When it goes to an outside shot of K.I.T.T driving away it is closed. (00:03:50)
Continuity mistake: When Michael rescues Bonnie and asks K.I.T.T to meet him, one minute it is night time, next scene bright daylight. If it was morning it wouldn't be that bright. This is where they have possibly used footage from a previous episode. (00:26:20)
Continuity mistake: When they arrive at the museum and start to unload K.I.T.T it is raining fairly hard. When it cuts to Bonnie and the Professor and the woman it isn't raining. This keeps happening throughout the scene. (00:38:15)
Continuity mistake: When the guy in the phone box is shot, and Michael yells for K.I.T.T, once K.I.T.T stops the front wheels are facing to the left. But when Michael drives off they are facing right. (00:13:15)
Continuity mistake: When the bad guy hits K.I.T.T with a log and he says "I beg your pardon", you can see a normal steering wheel inside K.I.T.T. (00:43:35)
Continuity mistake: When Michael drives by in K.l.T.T, if you look closely you will see that K.I.T.T has a normal steering wheel and a fake dash with no monitors. (00:32:20)
Inside Out - S1-E10
Continuity mistake: When you see K.I.T.T parked up talking to Devon there is a normal steering wheel on the dash. (00:29:00)
Continuity mistake: Just after Michael wakes up from being knocked out trying to stop the plane, he goes from the front of the Knight semi trailer (where all the computer equipment/office is) they are travelling in to get into KITT. He gets into the driver's side of the car (far side from the camera, indicating that KITT is facing towards the rear door of the trailer. However, in the exterior shot of KITT leaving the trailer, he emerges backwards down the ramp then does a 180 spin to go back the way he was facing when inside.
Continuity mistake: Throughout the episode, KARR has his own unique yellow voice modulator. However, when he is talking to the two robbers in their lockup and we see KARR mainly from the outside, the light flashing inside KARR as he speaks is red, suggesting that it is KITT (or at least the KITT prop, possibly filmed before the KARR's modulator was made or reused from elsewhere).
Continuity mistake: Throughout the episode, KARR doesn't appear to have a rear number plate as KITT does. However, in the shots of KARR smashing through windows/walls, he has KITT's ‘KNIGHT' plate.
Continuity mistake: When Michael falls off the plane and onto KITT's hood, he is not wearing his leather jacket as he tries to stuff it in the rudder to stop the plane from taking off. Very next scene, he awakens in the FLAG Semi, wearing the jacket that fell into the driver's seat as he fell off the plane. I doubt the doctor would take the time to put Michael's jacket back on.
Continuity mistake: When KITT lands in the back of the pick-up truck near the end of the episode, the internal shot shows the girl starting to get out of the passenger's side. But in the next external shot, she is getting out of the driver's side.
Answer: KITT didn't choose to go off the cliff in Goliath Returns, it just happened as he tried to avoid Goliath. Just 'cus it happened, doesn't mean It's gonna cure his fear of "flying"
