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).
