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: 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 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)
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)
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)
Nobody Does It Better - S1-E21
Continuity mistake: After KITT turns around to pursue Armand, the sensor goes from the usual side to side motion to a different pattern and back within a few seconds.
Continuity mistake: After the photoshoot Michael and Lisa are walking. Lisa's dress is on her shoulder, next shot it's off her shoulder and the shot after that it reappears back on her shoulder.
Blind Spot - S2-E5
Continuity mistake: After the KITT and Porsche chase scene, the police officer on the motorcycle comes to a stop in the dead-center of an intersection. But in the next shot when he looks around, he is barely inching into the intersection.
Continuity mistake: When Michael steps out of the car to talk with the gypsies his sunglasses appear and disappear randomly.
Continuity mistake: When Michael is getting Dr. Bergstrom out of Goliath, he steps onto K.I.T.T.'s hood and Bergstrom is to his right, in the next shot Bergstrom is to his left.
Continuity mistake: When Michael and Dr. Bergstrom get out of Goliath, the back door is still open. We see both get into K.I.T.T. at the same time since Bergstrom needs Michael's help walking on the hood. But once they're both in the car, the back door is closed and locked without Michael having a chance to. And if the door can close automatically or remotely, then it should have closed with Michael inside.
Continuity mistake: Right after Michael escapes from his cell, he finds KITT in the garage. Michael has KITT pop his hood to work on him, he asks KITT how he feels, the next shot shows KITT's scanner with the hood down, then it goes back to the shot of Michael and the hood is open again.
Continuity mistake: When Gina locks the door after Michael leaves, the close up of the lock is different than the one on the door. On the door, the top of the faceplate is right next to the deadbolt knob, but in the close-up there's a lot more space that you can't even see the top of the faceplate.
Continuity mistake: When Michael finds the stolen moving equipment, he parks KITT and then starts to climb down an embankment. The close-up shot of KITT's scanner reveals a tree in the hood's reflection. But when we saw KITT stop, there wasn't a single tree around.
Continuity mistake: When KITT is pushed over the mountain by the earthmover, you can see the front bumper is actually a stock Trans-Am bumper instead of KITT's normal one.
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"
