Other mistake: 99% of the shots when Michael presses the 'Turbo Boost' button, it's the same shot repeated over and over.
Knight Rider (1982)
1 other mistake in show generally - chronological order
Knight Rider [Pilot; a.k.a. Knight of the Phoenix] (1) - S1-E1
Continuity mistake: If you look closely at KITT throughout the pilot, the position of his scanner lens changes from being the normal scanner that we're all used to, and the scanner being at the very tip of the front bumper. (The latter case is because the car was used for a promo shots to sell to NBC, and after the show was picked up, they changed KITT's look, but still used the earlier shots).
Michael Knight: I need ya buddy.
KITT: Right away Michael.
Trivia: Even though William Daniels provided the voice of "K.I.T.T.", he was uncredited throughout the whole series.
Sky Knight - S4-E4
Question: In Goliath Returns, K.I.T.T. sky dives off the cliff. So why is he so afraid in Sky Knight?
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"
