To give a small but telling example, pointed out to me by my friend Ruth Oldenziel, an expert on the history of technology at Eindhoven University, Dutch drivers are taught that when you are about to get out of the car, you reach for the door handle with your right hand — bringing your arm across your body to the door. This forces a driver to swivel shoulders and head, so that before opening the door you can see if there is a bike coming from behind. Likewise, every Dutch child has to pass a bicycle safety exam at school. The coexistence of different modes of travel is hard-wired into the culture.

This in turn relates to lots of other things — such as bread. How? Cyclists can’t carry six bags of groceries; bulk buying is almost nonexistent. Instead of shopping for a week, people stop at the market daily. So the need for processed loaves that will last for days is gone. A result: good bread.

There are also in the United States certain perceptions associated with both cycling and public transportation that are not the case here. In Holland, public buses aren’t considered last-resort forms of transportation. And cycling isn’t seen as eco-friendly exercise; it’s a way to get around. C.E.O.’s cycle to work, and kids cycle to school.

It’s true that public policy reinforces the egalitarianism. With mandatory lessons and other fees, getting a driver’s license costs more than $1,000. And taxi fares are kept deliberately high: a trip from the airport may cost $80, while a 20-minute bus ride sets you back about $3.50. But the egalitarianism — or maybe better said a preference for simplicity — is also rooted in the culture. A 17th-century French naval commander was shocked to see a Dutch captain sweeping out his own quarters. Likewise, I used to run into the mayor of Amsterdam at the supermarket, and he wasn’t engaged in a populist stunt (mayors aren’t elected here but are government appointees); he was shopping.

For American cities to think outside the car would seem to require a mental sea change. Then again, Americans, too, are practical, no-nonsense people. And Zef Hemel, the chief planner for the city of Amsterdam, reminded me that sea changes do happen. “Back in the 1960s, we were doing the same thing as America, making cities car-friendly,” he said. Funnily enough, it was an American, Jane Jacobs, who changed the minds of European urban designers. Her book “The Death and Life of Great American Cities” got European planners to shift their focus from car-friendliness to overall livability.
