What is the name of a TV serial or movie that had a group of intelligent cars that could talk and drive themselves? As far as I can remember, the drivers were law-enforcers. They also had a big custom plane they used as temporary base.
Could it be Team Knight Rider?
It was a 90s spin-off of Knight Rider, featuring a team of crime fighters with talking, self-driving cars. They had a transport plane that they used as a mobile base.
