You and me both. You know how cats get tangled in people's feet? It's because they're evolutionarily designed to track one, and only one, moving object. While they're tracking one foot, the other takes them by surprise.
I'm spatially challenged too -- I'm strictly verbal. It's hard for me to look at something that's broken and figure out how to fix it, without laboriously composing (or being given) a verbal description. I have trouble with mirror images: can't tie a necktie if I'm looking at it in the mirror (thankfully I almost never have to wear one). My depth perception isn't very good either, though my eye-chart vision was better than normal in my youth.
I found out how spatially challenged I am through my study of karate. My transmission has two options: forward and reverse. I'm working on being able to move from side to side more, and at angles, too.
As an artist, I can figure out ratios and whatnot fairly well, and can copy something I see onto a page so all the spatial contours are duplicated. But ask me to find an address even with a map! I print out Google maps, lcarry other maps that have all the parks in green, and still get lost! On foot this can make me considerably late... :)
