Professional Piston Cup racer
Bruce Miller is a professional race car who competed in the Piston Cup Racing Series and replaced Winford Bradford Rutherford and Riley. He raced for the RPM team, but was eventually fired and replaced by Barry DePedal.
In Cars 3, Miller competes in the 2016 Piston Cup season, but begins to have difficulty keeping up with next-generation rookies, such as Jackson Storm. Storm's success shines light on the next-generation of high-tech racers, which are more physically capable than traditional stock racers, and like many other veteran racers, Miller is fired and replaced by Barry DePedal.
