The best aspects of Knight Rider's presentation are show clips peppered throughout the game. Whenever one of KITT's features is activated, a clip from the show plays. Drop oil slick or engage Silent Mode and you'll see a clip showing KITT deploying it from the show. I'm normally against games that do this, but it adds much needed style to otherwise bland visuals.
Outside clips from the show, the only other noteworthy element is the theme song. Driving around in-game is awkward, but hearing the synth-enhanced beat from the intro at least makes it sound fun.
