people, on average don't return the shopping cart

Perhaps I'm reading this too literally, but "on average?" This is a very flawed society, but I don't think I've ever seen the rando stranded carts equalling or outnumbering the returned ones.

I'm nearly 50 and have been to many, many parking lots including some truly forsaken ones. The parking lot at the Walmart near me is a travesty. People dump trash on the ground there, and I don't mean simple littering. It's so gross. It makes you feel like society is crumbling and that civilization was perhaps a mistake in the first place.

And yet...

I just returned from a quick trip there several minutes ago. I naturally thought of this thread (because I'm insane) while traversing the parking lot. I counted four unreturned carts, and several dozen properly corralled carts. The ratio was at least 10:1, possibly more.

This isn't "my" Walmart, but here's one near me that's notorious for being a bit of a Mad Max situation. If you switch to satellite view, you can see that even here the coralled carts seem to greatly outnumber the stranded ones.

While again not doubting that US is worse than many other countries, I wonder if some amount of this is due to our uh, organically sprawling road system. Because I have definitely been one of the people doing this at times, but it was always due to quite honestly misunderstanding what lane I needed to be in.

Anecdotally I've heard that our drivers are nowhere near the worst, but I don't have firsthand experience.
