In the world, a 100 years in the future, no one drives cars - instead, computer-controlled, electrically powered "AI cars" automatically take you where you want to go. However, when the AI cars mysteriously start to run amok, an organization called eX-Driver is established to figure out why.
After winning the domestic preliminary round, Lisa, Lorna, and Soichi advance to the eX-Driver World Race Competition held in Los Angeles, as the team representing Japan. As a bad omen, they encounter a reckless AI car the first night they arrive at Los Angeles. Although they successfully stop the car, the local police department is not very happy about the incident and insists to examining their cars overnight.
The story takes place on a world 100 years in the future, a few years before Lisa and Lorna joined the eX-Driver organization. In this world people do not drive, but "ride" computer-controlled electrically powered "AI cars" that automatically take you where you want to go. However, one AI car mysteriously starts to run amok. Now it is up to Nina and Rei — the main drivers for the eX-Driver organization — to solve the mystery behind this AI car...
