In essence, to "get to Radiator Springs" in the context of the *Cars* universe, you'd need to:
* Follow Route 66: This is the key. The films prominently feature Route 66, and Radiator Springs is located somewhere along its historic path. There is no real-world equivalent that's directly mapped; it's a stylized version of the route.
* Look for the signs: The films show various signs, landmarks, and small towns along the way, though these too are fictional. In the game *Cars: Mater-National Championship*, there are specific routes shown.
* Embrace the journey: The journey itself, with its unexpected turns, breakdowns, and roadside discoveries, is as much a part of getting to Radiator Springs as the destination.
Essentially, there's no GPS coordinates or a specific map you can follow. It's a matter of following a fictional Route 66 in the *Cars* world.
