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.

Continuity mistake: When KITT first stops talking the Auto Normal and Pursuit mode indicators change from old fashioned very angular with a different font and switches to the newer rounded rectangle with then new font. It does this several times.Benjamin Lesley
