The story takes place in around the year 2000 AD. Amongst the hoards of good old gasoline-powered automobiles, "cyber wheels" appear, equipped with non-polluting engines and advanced navigational systems called "cyber systems." Cyber wheels provide a safe and comfortable automobile society for humans.
By now, all racing vehicles are furnished with highly sophisticated AI (artificial intelligence) computers, and are called "Cyber Formula." A racing machine of this "Cyber Formula" type can at best be operated by a child who has never driven a car. As long as he follows the instructions given by the computer, it will take the child to his destination. If there is any danger, the computer will automatically avoid it, or change the car's scheduled course. Moreover, this safety feature only works in the context of ordinary navigation.
