Vertical versus horizontal.
New York is the most vertical city in the Western world — everything stacked in Manhattan, crossable on foot and by a 24-hour subway. Los Angeles is the opposite: 500+ square miles of sprawl with no obvious center, stitched together by freeways. In NY you don't need a car and it would be foolish to have one. In LA you don't survive without one. That single difference defines the rhythm of both itineraries.
