Yes. Every city and individual case is different. Often it is a case of convenience. Here in ATL if I am going downtown I take the subway MARTA from a station not too far from where we live; but I drive to the station and park there because the bus would require a walk a wait and would be in slow traffic getting to the station. If I am going to be in traffic, I might as well be in my own car listening to the radio. To the airport, I always take the subway - very convenient and direct. So it is a mixture of convenience and easy access to transit.
