I've no idea. But flipside, I know quite a few sighted people who can't walk around a rectangular block without losing track of which way north is. Or can't visualize that (say) their master bedroom closet backs up to their kitchen. Or other facepalm-worthy visualization failings.

> without losing track of which way north is.

I blame my childhood. Everyone always said the Pacific Ocean is to the west. So naturally the direction I went to go to the beach on the pacific ocean should be West. Especially when the north/south freeway crosses the street I take to the beach at a pretty good angle (well it's more like 45 degrees). Turns out I actually go south to go to the beach, the freeway is roughly parallel to the coast and north/south freeways sometimes travel due east/west and I have a real hard time with cardinal directions, and even if I understand where the directions are when outside, when I enter a building, especially if I go up stairs or an elevator, my sense of where the cardinal directions from inside the building is likely to be way off.

Thankfully, there's not a big impact from not knowing where room walls are relative to each other. :P

I have never been able to use cardinal directions but I am very good at mental visualization and manipulation of 3d objects
