Fascinating article. Thank you!
I've been this way my entire life as is the woman featured in the article. I've always referred to myself as being Directionally Dislexic. That isn't a "diagnosis" just simply a term I've made up to help explain why I get lost so easily.
I've shared many of the experiences of the woman in the article. I've never kept it a secret though. Everyone who knows me knows that I generally need written directions and even then, things can be sketchy
If I'm somewhere that I'm familiar with landmarks, I can generally find my way to where I need to go. This isn't from having a sense of direction - it simply tells me which direction I need to head until I find familiar streets or other landmarks. For example, when I'm in San Francisco if I can see either the Golden Gate or Bay Bridge or the Transamerica Pyramid I know what direction to head.
OP, like your friend, people who know me simply don't send me off on my own if it can be avoided.
The invention of GPS has been a game changer for me as far as driving.
