Hands free: The Audi Sport Quattro Laserlight concept car features compact sensor and computing technology that lets the car pilot itself.
 
 Carmaker Audi showed off a book-sized circuit board capable of driving a car on Monday at the International Consumer Electronics Show (CES). Audi claims the computer, called zFAS, represents a significant advance in automation technology because it is compact enough to fit into existing vehicles without compromising design.
 
 Several different Audi vehicles equipped with zFAS drove themselves onto the stage during the presentation, and a new concept car designed to showcase it was also introduced.
 
 The car, called the Audi Sport Quattro Laserlight, is capable of what Ulrich calls “piloted driving” but betrays no outward sign of being different from a conventional vehicle.
