This is interesting, when I lived in London (20+ yrs ago) I had an AtoZ at home and a street map in my car. I got to know London pretty well in terms of walking around. At lunchtimes I would try and see how far I could walk in the hour and what interesting landmarks I could pass. I pretty much learnt to drive in London and would cruise around at night just because it was a cool thing to do when you'd just got a car. When I've been back more recently, I still remember my way round for the most part but I find myself having to check myself by phone every few minutes, so it's more the confidence that I've lost. Most of the original knowledge came not from a map but just wandering aimlessly and remembering. Strangely I have a similar approach to hiking in the hills and often just wing it, although I generally have both a map and a phone app OS map in my bag.
