No one has answered my question. Aside from a small questionable dialogue... what actual proof? what landmarks? what signs? do we have stating that Radiator Springs is located in ANY specific place, other then the U.S. and in the Desert. Had it not been for the 66, we could have placed it in Mexico, the Sahara, the Gobi, thing is it's a desert and there wasn't a lot of distinct landmarks. Personally I think that was done on purpose, so it could be anywhere! Meaning it could be CA, AZ, NM, TX... WE DON'T KNOW! Also as noted, it is not always evident where you are... you're in the desert... that's about it.
