Yeah but most places in Europe don't have 16 lane highways. And there's quite a lot of old tracks that you can cycle along even if the main roads don't have separated bike and traffic.
In the US you have the, guaranteed to cause collisions, grid layout and that's basically it. If the Americans could get a hold of the idea of not driving into each other they could also have roundabouts.
Maybe biking is an exception, but for public transportation and walking, it is absolutely true that pretty much all of Europe is much better. It’s not even close.
