I'm always wondering how Americans feel traveling to Europe and being able to walk in cities. It must be so surreal that they either have to move, or they can't fathom that these cities are practical to live in.
All of Greece is car oriented. Of course if you stay near Acropolis you get the impression of walk-ability. Spain outside of the historic city centers is car oriented. Average mileage traveled by car per person in Germany is about the same as is in Canada.
I can continue your generalization about my home city - Montreal. Which is walk-able .. but not really, see the second part here https://www.youtube.com/watch?v=_yDtLv-7xZ4
In fact, if you use their transportation network, you actually get somewhat better treatment: in all of the parks, there's a shorter walk to/from the transit terminal than to your car, and in one of them (Magic Kingdom), you are required to park a distance from the park and take a connecting ferry.
I am in Madison, Wisconsin and we have a number of areas like State Street where walking is the norm: https://visitdowntownmadison.com/
By and large this is not the case but it isn't as if it's unimaginable what it would be like.
Europeans must marvel at being able the size of living accommodations in the US. They can not even fathom in their brains what it's like not to be crammed into a tiny 20sqm flat.
