Watching the citizens of Radiator Springs drive through town is one of the most simple, straightforward charms of Cars Land. Human guests politely make way for the residents, and there's always an honor guard pit crew present to gently make sure the path is clear. These frequent character appearances seem amazingly casual, and happen often enough to feel like a normal part of a typical, easy-going day in Radiator Springs.
Lightning McQueen and Tow Mater both talk to the guests as they pass, and make comments about the various shops and attractions along the way to and from their meet-and-greet appearances at the Cozy Cone Motel. Combined with the engine noise, these frequent trips along Route 66 and Cross Street add even more energy and character to the bustling little town.
