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.

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.
