White Bird - S1-E19
Visible crew/equipment: As KITT goes to jump over the fence of the airport, the helmeted stunt driver is seen, as well as part of the ramp pops up into view. Also, you can plainly see that it's the lightweight stunt car, as you can see though it from the bottom.
Visible crew/equipment: As Michael and Robin go to get into KITT on the firing range, the filming crew and equipment are reflected on the light cover on the back end of the car.
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.

Revealing mistake: When K.I.T.T turbo boosts near the end when chasing the 4x4 you can see the camera strapped to the side of the car. (00:42:35)
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)
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"
