When KITT shows the heat signatures of the getaway car where Agent Rivai is in the trunk, just before Mike says: 'She is not moving', she actually turns her head.

Goof: When Graiman scans the impostor's hand the loudspeakers are counting down and say "Four", but when KITT tells Michael the countdown is aborted, the monitor behind KITT shows there are 14 seconds left.
At the beginning of the episode, Mike is watching the Dallas Cowboys and Seattle Seahawks playing on KITT's windshield. Only Dallas and Seattle did not play each other until 11/27/08, over a month after this episode aired. These two teams last played each other in the 2006 postseason, wild card playoff on 01/06/07.
Mike's cover name is Jack Miller.
We find out it is Sarah's birthday in this episode.
Goof: During the car chase, KITT says there is a semi truck obstructing the road ahead and that the assassin will collide with it. Although a semi does enter the road, the actual obstruction is a pickup truck.
When we first see the antidote, it is bright blue. However, when we see it the second time, before the vial is smashed it is dark purple.

Trivia: When Skyler first shows Mike "The North Beach", the surfer who gets pulled under by the wave lets out the Wilhelm scream. This is a stock sound made famous by Ben Burtt when he featured it in multiple blockbuster films, including Star Wars and Raiders of the Lost Ark.
Goof: When Michael and Zoe are first driving down the beach, the green screen can be seen reflected in KITT's hood.
Goof: As Skyler leaves Mike to die in sea, we see KITT coming down the hill with the two surf boards on his roof. Next time we see KITT at the beach there are no boards.
Goof: The first time that Mike is in the bar and speaks to Ian Chang's girlfriend Celine Lea. When Ian enters he tightly grabs Celine by her right arm. The second time Mike is in the bar Celine shows her bruise mark to Mike. However it is on her left arm instead of her right.
When KITT is running a background check on Celine Lea, the display has the word "HEIGHT" misspelled as "HIEGHT."
Nitpick: Sarah throws the key that KITT duplicated to one of the Chang brothers. However, a jingling sound can be heard, though KITT only made a single key.
