When Michael is ushering Sarah toward the rear of the cargo bay after securing her parachute, within several seconds of the angle change away and back to the pair, Michael's own parachute changes from not on at all, to on and fully secured.
In the scene where KITT is about to explode Micheal Knight orders KITT to tell the pilot and co-pilot to bail out of the aircraft. About 5 seconds later KITT's self destruct is aborted, but nothing is said to the pilot's and even if it were standard practice is for the air crew to bail out as quickly as possible after the order is given, the pilots probably would have been out of the aircraft in 5-10 seconds.
In this episode the diagram that K.I.T.T. brings up for K.A.R.R. looks like a robot on four wheels. In the original show, which this show is supposed to be a sequel to, K.A.R.R. was almost identical to the first K.I.T.T. in every way. However, K.A.R.R. may simply have advanced it's transformation techniques to better reflect its programming and 'personality'.
K.I.T.T.'s memories that he is reviewing are scenes from the show, and can't be his own memories because they are exterior shots of him.
