Karr is the evil prototype of KITT from the 1980s television series Knight Rider, a self-aware car built before the heroic KITT and programmed without regard for human life. Michael Knight, the series hero, repeatedly confronts the rogue car, making their exchanges a memorable part of the show for fans of retro science fiction. Short clips of Karr's cold, computerised dialogue have circulated on soundboards and in fan edits for years, because the contrast between his polite wording and sinister intent makes a perfect dramatic sign-off.
