Not true along the east coast. Those states have been urbanized since the 1700s.
You mean like New York, Boston, Washington, D.C. and places like that?
As Sam Kinison might say, "MOVE TO THE TRANSIT!" If one mode is no longer available, affordable, or usable, restructure your life so that you can take advantage of another. Adapt or die, that's the way life works.
In that case, I hope you're independently wealthy so you can continue to live in your suburban sprawl without having to spend 10 hours a week stuck in freeway traffic.
Your tune will change when the current road system becomes so overloaded with cars that it is useless. Here in LA, by 2025, the average freeway speeds are predicted to fall by more than 50%. A trip that takes 45 minutes today will take over an hour by 2025 - you can imagine what that does to those Inland Empire trips that already take two hours.
But go ahead, feel free to stick with your personal automobile. While you're moving along at 10 MPH, choking on exhaust fumes, I'l be the one waving to you from the train as I sail past you at 75 MPH on a private right-of-way with no obstructions. :)
