I don't think you can blame the attitudes of the wealthy here. My impression is that their attitudes on this are  no different than those of the rest of Americans. In most of America they don't want to ride mass transit. In NYC,  the greatest single concentration of wealthy people in the US, they do.  Like the rest of New Yorkers they're acting rationally - the mass transit system is good, driving sucks. In areas where mass transit sucks only those who have to will use it. The only difference is that they use cabs  more often outside of rush hour (regardless of whether the cost matters, spending far more time to get where you want to is generally not appealing) and tend to shell out for the luxury of owning a car for out of town trips rather than relying on rentals.
