Oh, and wasn't there a KITT-like motorcycle?
Dear God, help me. I know the answer to this one.
In one episode KITT and Michael had to work with a guy who was a computer programmer or something. A real geek. At the end of the show, they showed his scooter painted black with the red, swishing light on the front. I believe it was called K.N.E.R.D. Oh the 80's.
