New York City is the only city in America (or maybe the world) where people are expected to have a general understanding of the geography in casual conversation.
Like why do I feel like I’m supposed to be able to name the seven boroughs? I can’t tell you anything about L.A., Chicago, Boston, etc.
Edit: to clarify: I mean that everyone in America are expected to know NYC. Not just New Yorkers. Obviously everyone should know the layout of where they live.
For many, maybe even most Americans, NYC might as well be a fictional place. It's featured heavily in countless movies, TV shows, books, etc. It's more common than Westeros, Middle Earth, or Hogwarts. And people are expected to understand these settings, at least as much as NYC.
And that's all before you consider places like Batman's Gotham that is very clearly NYC.
