Ownership and use are two totally different things though. I lived with a wealthy family in Hamburg and they owned 2 cars and a vacation home in Southern Germany… and they seldom drove except to the house in the South (sometimes) and, maybe, once a month for a big grocery run. The kids rode bikes to school, the couple took the U-Bahn to work. I saw the same things in Spain and Switzerland. Obviously these are just anecdotes, but the fact is that the super-majority of developed countries do a much better job at creating infrastructure to avoid car-use than the US. I would wager Japan is similar. I quick google search tells me the average Japanese car owner drives about 3,700 miles vs the average American driving over 13,000 miles a year.
