I used to be amazed by the idea that there were people that couldn't do this. A good map/atlas has an index of street names and what pages grid cells they're on, and you can trace any familiar road trip with your finger (or a highlighter if you must).

Now I know that some people have a lot working against them. Some can't visualize things in their head, have no clue which way North is, or imagine what their current location resembles on a 2D map. There's also a kind of "navigation sense" that some people have and/or learn where your perception of space is in constant comparison to near and distant landmarks, even when indoors. People that can do these things are not afraid of liminal spaces, can easy find hidden rooms in structures, know exactly how big their car is, can improvise new routes between distant locations with ease, and being lost is a temporary problem at worst.

Edit: I had an ex that had very poor spacial perception, so that's a thing too. There was an argument over whether or not a moving box would fit through a doorway when carried. Critical thinking aside, a complaint was made when seeing the box sitting alone, packed, in the middle of an otherwise empty room. From outside the room, this person was unable to accurately compare the box's size in relationship to the doorway's dimensions, and insisted it was too big to leave the space. It was as if their mind was unable to pull together enough context to get an accurate frame of reference. I think this spacial perception ability applies to navigation as well, and may explain why some people struggle with it.
