It makes a lot of sense to me though. America, like Europe, has a huge amount of diversity in things to do and places to go. It would take a lifetime to see everything worth seeing in America and I can see why the effort (and cost) of going to say Europe or Asia wouldn't seem appealing when you can go see something domestically like the Grand Canyon, the museums in DC or any of the numerous different cities/states.
So Americans don't have as much reason to travel I think and given that the American economy is so enormous and the country is physically isolated from the rest of the world, ultimately, the state of the world outside America doesn't impact an American as much as it does a European.
This isn't to say that this is right but I think this at least somewhat provides some reason for the way things are.
This is likely selection bias, at least in part. If you were to live in Europe, the proportion of Europeans you know who speak 3+ languages would go down, the proportion of Americans you know who speak 2+ languages would go up.
BTW - 25% of the Americans I know speak Chinese. Also selection bias: I live in China and have never lived in the US.
I'm not sure if you intended to say Americans are intentionally insular, but if so, that's definitely not the case. It's just a side effect of being able to travel 2000 miles easily without ever leaving the US.
Additionally, in order to travel to another country other than Mexico/Canada, airfare alone for a family of 4 will be like 10% of the average annual household income so it's not really affordable for most Americans.
This is very much specific to what country in Europe you're talking about and what field of work you're in. Over here in the UK, there are a lot fewer people that speak multiple languages than in say the Nordic countries or Germany.
We get far more news about the US than we do about Europe, US movies and TV are mainstream while European movies usually only get niche middle class art house distribution, our singers sing with fake US accents, and it used to be much easier to decorate your living room with photos of Brooklyn Bridge than of European landmarks - until we started putting union jacks on everything.
As far as many English people are concerned the US is full of sexy super heroes, while the EU is full of immigrants, shifty foreigners, bureaucrats, and smelly cheese.
So it actually makes no sense to compare SF to London, because in many ways (excepting the weather, the age of the housing stock, and possibly the social signals used to indicate class) they're more similar than different.
Comparing SF to Berlin, Barcelona, or maybe Lisbon might be more revealing.
I don't even mean that Europeans travel more because they jump a few European borders. Most European people I know have taken a whole year out after university to travel the entire planet, trying to see and experience as much as possible, from far Africa, to Asia and even America. I travel a lot myself and whenever I cross continents I always tend to meet the same people: Europeans (English, Swedish, Germans, French, etc.) and Australians. I rarely meet an American. Mostly I came across Canadians in South and Central America, but that was it.
This is not true of most European people I know. Yes, some people do it, but it's a very small percentage of the population, concentrated among the wealthier part. Even in the UK it's only a small part of the population that does it, never mind in poorer countries like Greece. I do think the majority of Scandinavians I know have done the "gap year" trip, but not the majority of British, Polish, French, Spanish, or Greeks.
My view of what's normal in the UK, though, may be different because I don't live in London.
In London I would put that number closer to 25%, but that says more about the type of people that move to London than it does about Europeans in general.
This month, there are flights to France for £5 each way.

Yes, this entire post is about generalizations. I figured that was sort of implied.
Obviously, we're dealing with stereotypes. If you're this repulsed by it, I'm very interested in knowing how you'd dissect "culture" without resorting to generalizations?
Mods: Is there a way to mute/block users?
Great question. Coming from Mr. "I have no experience with Europeans, London, or San Francisco, but here's my opinion anyway".
To contribute: I've spent a considerable time in London and the original post has left me unconvinced that the author has spent any time in London except as a tourist and living vicariously through other peoples' blog posts.
