On the contrary I think it fits most of the USA save for maybe the Southern States. As an Eastern European myself I'm interested in knowing excactly which stereotypes Americans hold. They might be mostly true as well.

The problem with measuring USA, China, Russia is that they are so large and diverse that you'll get very different results depending on where you are. It would be like saying "Europe". Apparently, they used the largest 5 cities in each country, which I suppose helps make for more comparable results. But for example in Texas I'd expect the results of San Antonio/Austin/Dallas to be significantly different (they are culturally) even though they are only separated by only a few hundred km.

However, I can say in the US one of the biggest differences is just rural vs urban. The likelihood of things disappearing in cities vs towns is higher, I suspect because fewer people know each other. I'd also say that changes over time are fairly dramatic. Many people in the US didn't lock cars or homes until the 80s and 90s or even 00s.

No it wouldn’t, not for the US. Europe has 50 different countries and 24 official languages. The US has two widespread languages and apparently has so little cultural variety that you can move across the country without any major culture shocks (at least I haven’t heard any).

It could sometimes make sense to, at a distance, talk about certain regions like a monolith, like for example Scandinavia. But it makes no sense to talk about Belgium and Greece in the same sentence.

Interestingly people often generalize “Europe” based on what happens in the handful of 4 million+ cities.

Hmm, is this why there are subtitles on reality TV shows based in the south? Suburbia is fairly uniform, but not so much the urban or rural areas.

I would expect culture shock between NY and Dallas, Seattle and Atlanta, much less Salt Lake and Boston. I can get Cajun drawl, but not Southie without a fair bit (not quite Glasgow levels) of concentration.

There are (sometimes, rarely) subtitles on Norwegian TV for Norwegian dialects. Doesn’t make it diverse (homogeneous as Americans like to say).

You should visit. A dialect that millions of people speak separated by thousands of km, income, and livelihood is not equivalent to the language difference between Swiss Cantons, it's closer to the difference between Lombardi and Napoli. Just look at the driving, forget language.
