I thought my wife's aphantasia is related to her difficulty in orienting a map and figuring out where she is on the map. If GPS is off by half a block and/or the magnetic compass has the map mis-oriented by more than 45 degrees, then it's very difficult for her to compensate. Certainly, when I navigate by map, imagining the street scene overlaid when looking at the map and imagining the map overlaid when looking at the street scene are huge aids to navigation. She's not able to generate that augmented reality in her imagination, and I attributed that lack of mental augmented reality to her difficulty in using maps.
Generally, I'd prefer to navigate and let my wife drive, but she's used to driving in countries where they drive on the left, and I'm used to driving in countries where they drive on the right. Also, if a manual transmission is significantly cheaper to rent, then I end up driving, regardless of which side of the road the locals drive. More than once, I've down-shifted while turning on my wipers instead of my turn signal while entering a roundabout. At least car manufacturers don't flip the shift pattern right-to-left when changing which side the steering wheel is on.
