Just a theory. I have no reason to believe this is true. But that would be awesome.
It might be cheaper to engineer this ^^^ than to engineer a fancy motorized roof rack that moves out of the way so the doors can open. Also has the added benefit of capturing those people that think the falcon doors are just too fancy.
