At one point I was doing quite a bit of driving between New Orleans and a worksite in Pascagoula (just across the MS/AL state line from Mobile). This wouldn't have been very interesting at all given Pascagoula was very spread out and I absolutely needed a car once I was there. And it's a pretty straightforward ~2.5 hour drive.
Taking the train to NYC by contrast a car is, in general, actively a negative thing once you arrive.
