In the KARR episode, at around 31 minutes, 50 seconds, during the chase scene (KITT is chasing KARR), Michael jumped off of KARR and into KITT and is now driving KITT. Yet, a few seconds later, they show Bonnie in KARR with the bad guys and in the rear-view mirror, you see Michael (well, a stunt man) dangling on the roof still.
This whole series has bad editing. I've been watching this on UHD, and just noticed this episode the other week.
Also, they keep re-using the car from the stunt show episode, when KITT has the stars on. And the funniest one is when they use stock footage, like when a car goes off a cliff, they use this old footage of some 1950's style car that wasn't even in the episode. And they use the dam breaking from Superman: The Movie in another episdoe. In the Devon got arrested episode, when he breaks out of jail, they clearly show a guy in a helmet making a jump. I love watching this show for the mistakes.
