I've lived in the city, mind you not a large one, but I noticed most everyone around me in my home at the time. From the guy 2 doors down that yelled at his dog to get off the couch anytime I had my window open, to sirens going off a few times a night, it was enough to notice how quiet the country is when the loudest thing at nights is the interstate 10 air miles from my home or the occasional owl that roosts in a tree in my back yard.
Buying a fare on plane, train, or metro is just essentially a one time license if you think about it. My point is that the traveling on time frames for departures and limited destinations for planes, trains, and metros is more restrictive over leave at anytime and go anywhere most anywhere on your continent of a personal vehicle. Each mode has their place and advocating for the elimination of any seems shortsighted.
