In Pixar’s Cars, Lightning McQueen accidentally damages Route 66 near Radiator Springs.
While being transported to California, Lightning falls out of Mack’s trailer and becomes separated from the truck. He ends up on a road near Radiator Springs, where a chase causes him to tear up the pavement. The local judge, Doc Hudson, orders him to repair the damaged road before he can leave town.
Route 66 is a historic American highway that originally connected Chicago and Santa Monica. Although much of the original route was removed from the federal highway system in 1985, it remains a major symbol of American road travel and roadside culture.
Cars uses Radiator Springs and its surrounding road landscape to celebrate that history. The fictional town is inspired by communities along old Route 66, especially the kinds of businesses that declined when newer interstate highways diverted traffic. The damaged road is therefore both a plot device and a reference to the film’s broader road-trip theme.
