Yea, that's why I stated in my previous post...
"...might actually be a decent place for somethin' like that."
Because it is outside the "wheel" and separated by water and kinda' out in the boonies from the rest of the park. But, ultimately, it is best left for some other future MK expansion.
Plus, all the lands in the MK are based on general themes and not specific franchises. The movie-based attractions are, generally, placed in the appropriate land to which they most closely relate.
But yes, thematically, a Carsland would make a lot more sense in DHS.
