There's far too much variance to have a European standard. I vaguely recall seeing bandwidth-capped plans in the country I'm living in now last time I was shopping for internet plans, but I'll have to check again.
That 20 Mbit/s driving across remote areas probably wouldn't even hold true for Switzerland.
But yes, overall I'd say the US definitely has worse home internet infrastructure (though it's unfortunately still not as bad as some other developed countries).
From my experience in Switzerland a lot of times holds true for me(in city however I can achieve a lot more then Mbit/s)
But for sure it depends on location, but for now in the remote areas I have been there it worked like a charm.
But recently in a relatively big city in US, i was at measly 5 Mbit/s.
However I am sure there are as always areas with low or maybe even nonexistent coverage in any case in any country. But the percentage of that can cover widely practically speaking.
