I feel Cars is so specific, though, as to it being hard to really get over the IP. Coco, for example, can be read as being themed to Mexico, Encanto and Indiana Jones seem to be going into a Tropical Americas land, and even Avatar or Galaxy's Edge can be read as more generally sci-fi/outer space environments. Carsland, though, is full of oversized references to parts of cars and things related to them in a way that is very specific to the films. On one level it is based on Route 66, but it is so adapted to everything being a reference to cars that there wouldn't be space for anything that wasn't a part of that world if they decided to drop the specific connection to the IP for the land.
