Americans will never walk.
Where I live, today's high temperature is lower than the low temperature in Amsterdam.
In August the average low temperature is higher than the average high temperature in Amsterdam.
Nobody, not even the hardiest Dutchman is going to walk or cycle when it is 27C at midnight in the summer and 0C at the warmest in the winter with four months of "Amsterdam weather" sprinkled between summer and winter.
Plus there's geography. My house is 21m above sea level, 3m higher than the highest point in Amsterdam, and I live 500m from the sea at the very beginning of the rollercoaster of hills and valleys the glaciers carved into the landscape here.
To walk or cycle to a store would require several Col du Tourmalet-class hill climbs (that's only a slight exaggeration) along the route.
Everywhere south of me is hotter, everywhere north of me is hillier.

Compare Amsterdam to DC a well-known "swamp" in the US that most people would consider one of its flatter cities.

Don't be thrown off by the scale: yellow in Amsterdam (of which there is none) is 25m and yellow in DC (of which there is much) is 78m.
