KARR (Knight Automated Roving Robot) is the name of a fictional, automated, prototype vehicle featured as a major antagonist in two episodes of the television series Knight Rider and was part of a multi-episode story arc in the 2008 revived series.
KARR is the prototype version of KITT, originally designed by Wilton Knight and built by his company Knight Industries. Upon completion of the vehicle, KARR's CPU was installed and activated. However, a programming error made the computer unstable and potentially dangerous. The project was put on hold and KARR was placed in storage until a solution could be found.
Unlike KITT, whose primary directive is to protect human life, KARR was programmed for self-preservation, making him a ruthless and unpredictable threat. He does not appear as streetwise as KITT, being very naive and inexperienced and having a childlike perception of the world. This has occasionally allowed people to take advantage of his remarkable capabilities for their own gain. Despite this, he does ultimately consider himself superior (always referring to KITT as "the inferior production line model") as well as unstoppable, and due to his programming the villains don't usually get very far. KARR demonstrates a complete lack of respect or loyalty, going so far as to on one occasion eject its driver to reduce weight and increase its odds of escape. (taken from Wikipedia)
