It can, when cities are not built with dumb land use patterns.
I am moving to an apartment 50km away from my workplace. Commuting by car or by train will take around the same time (~50 min door-to-door), but the car will be subject to random traffic, hunting for parking spot, stress, etc. Oh, and the train is several times cheaper.
How is that relevant? No one commutes from NY to LA everyday, much as no one commutes from Berlin to Munich everyday.

Yes, and that's what I mean by "dumb land-use patterns". That people living in suburbs are not technically within a city's boundaries is a distinction without a difference. Land is wasted to highways and parking lots no one can cross without a two-ton machine, useless lawns no one really has time to enjoy or maintain, dumb McMansions that cost and arm and a leg and so on.
