I would also prefer it at Hollywood Studios.
However, I was approaching it from Disney's POV, and they have no large plans for WDW's worst park by a mile, HWS, which is why I included it here.
Rather than dropping half a billion on a hodgepodge land of Coco and whatever other random IP, I'd infinitely take arguably the greatest land outside of Tokyo DisneySea. That was my point, and placemaking-wise it would fit pretty well opposite of Big Thunder Mountain.
However, I don't feel like Cars Land feels like a single IP land in the ways the Potter and Star Wars lands do since it has a groundedness that makes it not even feel like one, while also having a heart to it on account of the IP that I feel has only ever been captured in Disneyland Park, so I'd more than welcome it.
