When KITT is pushing the two Mercedes and the Renault Fuego out of the way, there is rubber padding taped to the rear bumpers, but not beforehand or after.
When KITT jumps off the cliff to rescue Michael (approximately the 26 minute mark), it is not a black Trans Am, nor does it even resemble one. It is in fact stock footage from Der Teufel auf Rädern (1977), the car from which is another George Barris custom build. The producers owned the rights to both Knight Rider and The Car. The same footage was used earlier this season when KARR drives off the cliff in Trust Doesn't Rust (1982).
K.I.T.T. refers to his winch as a pulley. K.I.T.T.'s winch is actuated by an electric motor and is not a pulley.
When K.I.T.T. locates the assassin near the end, he states the man has a "high powered weapon". The assassin clearly has an Armalite AR-7, which is only a small caliber .22LR and not a high powered weapon.
In the first couple of minutes of the episode, Michael Knight is trying to put on his tie, before the female guest walks into the house. However, the actress can be seen in the next room, holding her spear-gun, and casting a shadow, before she is shown entering the house and then his room.
In the opening scene, as Michael adjusts his tie, a woman in a swimsuit ascends the stairs with bare legs. This was likely a body double, because when Maria Alonso enters the scene, she is wearing darker-toned pantyhose-style leggings.
When Judy Landers jumps out of the car it is no longer her, but rather a stuntman dressed in woman's clothing and a blonde wig.
On K.I.T.T.'s computer screen, the Cadillac Seville is represented by a cartoon red Formula One racing car seen from above. It's actually from a video game, Rally Speedway.
Phone book close up shows a small patch of 555 numbers in a larger font than the rest of the likely real entries on the page.
When the phone book close-up is shown, at the bottom of the "555" entries there is one entry which is not in alphabetical order like all the others: "Palmer D W" follows "Palmer John W".
The stunt man who ties up the bad guy at the end of this episode's final chase scene is wearing black shoes in the far-away shots, but David Hasselhoff is wearing tan Nike sneakers in the close-up shots.
When Michael is driving in the dirt, you can hear the sound of tires squealing on pavement.
We hear the sound of a gunning engine as K.I.T.T. revs up to turbo-boost off the cliff, and then we see his accelerator pedal go down.
When Michael asks KITT to pick him up at the party, KITT has to maneuver around blocked cars. KITT pushes the bumper of these cars, and a cushion is clearly visible on each bumper.
During the car/horse chase, Judy Landers' lapel-mic is clearly visible.
At the party, after K.I.T.T. has pushed the other vehicles and then reverses, a quick view of the interior of the car clearly shows 2 hands on the steering wheel.
As the white el Camino pulling the horse trailer turns around you can see the shadows of the crew and cameras.
When K.I.T.T. is zooming in on a map of South America and tells Michael that he's looking at "the militaristic state of San Marada", the map shown is very clearly zooming in on Brazil, complete with the country's name in bold print.
K.I.T.T.'s winch has been able to pull whole cars before. In spite of this, it overheats while bearing less than a quarter of the weight of a car while pulling Mr. Knight and Ms. Bradburn up a slope.
When Michael arrives at party, as he refuses to allow the valet to park KITT, the boom is visible over the car.
Michael says "Your average bum doesn't wear a Swiss watch", but the bum in question is wearing a simple Japanese digital watch; the only remarkable thing about it is the gold colored bezel and bracelet.
