If you’re living in NY or SF, it makes sense to not drive. But just about anywhere else, save for Chicago, you should definitely drive. In my experience, the people I knew who didn’t, were mama’s boys. They were the type whose moms always cleaned up their messes, never disciplined them, and always babies them. They would latch onto friends, later in life, who they could depend on to do the same thing. This meant, they always relied on friends to drive them around. They simply knew they could get away with it. Inconvenient? A bit. But then they never had to be the DD when we went out drinking. They could always enjoy themselves. They never had any responsibility really.
