What else might I not know?

I'm a middle aged Australian who has never been to the States.

There are some language and cultural differences that are very widely known and I've been aware of since childhood, either from media or just because everyone knows those things.

But there are other interesting things I only heard about quite recently.

Examples: Public toilets often aren't private because the cubicles have large gaps around the doors?

There's some kind of advertising at gas stations that you watch while filling your car?

If you have an accident while driving, the fire brigade comes?

Grits is something like muesli?

So, what other weird, cool, or unique things are there that non US people might not know about, or are often surprised by when they visit?
