In Pixar's Cars 3, Thomasville is the fictional town associated with Doc Hudson's racing history.
Lightning McQueen travels there while searching for a way to regain his competitive edge. The town is connected to Doc's earlier racing career and to Smokey, a mechanic and former crew member who understands how Doc learned to compete successfully.
Thomasville provides a bridge between the first film and Cars 3. Instead of simply copying Doc's old methods, McQueen learns why Doc adapted his technique and how mentorship can continue across generations. The town is separate from Radiator Springs, McQueen's home base, and its appearance helps reveal details about Doc that were not fully explored in the original movie.
