And mass transit adoption keeps growing for the workforce. Because sitting in a car in traffic sucks that much. So we make self driving cars and all those people pile into personal vehicles? That only exacerbates the problem.
The reality of it all is extremely painful
However when I go into Manhattan for non work related activities, my wife and I (and nearly all my friends) always drive.
The NYC transit situation is decent and tolerable, but still very unpleasant. If I want to enjoy a night in the city, the last thing I want to do is deal with the transit system.
Dealing with mild to moderate traffic within the confines of my (admittedly pretty nice) car is not very painful at all.
We look at the traffic situation before going in. If it's terrible, we just cancel our plans in Manhattan and do something else.
