your comments show the power&depth of this analogy. the challenge for an effective local driver is to avoid routine and remain cautious and flexible to react to the changes in his leaned-by-heart territory: new rules, roadsigns, changes in traffic organization, self-driving cars etc.

True. I may be the best driver in Slovenia, but when I want to drive to Manhattan, I will have a bad time (pun intended). I will learn to drive there faster than somebody who is also bad in Slovenia, but I will still need my time.
