Knight Rider [Pilot; a.k.a. Knight of the Phoenix] (1) - S1-E1
Devon Miles: Welcome aboard the Knight 2000.
Michael Long: Thank you. What's all this? It looks like Darth Vader's bathroom.
Devon: It's a one-of-a-kind car, Mr. Long. It is the fastest, safest, strongest car in the world. It is also completely fuel-efficient and it is operated entirely by microprocessors, which make it it virtually impossible for it to be involved in any mishap or collision. Unless, of course, specifically so ordered by the pilot.
Michael: Pilot? Don't tell me this thing flies.
Devon: No, but it thinks.
Michael: It thinks? My car thinks?
Devon: We like to think of it as our car.
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"
