That sounds like a massive waste of money to me. Those first 2 regions are full of cities with massive sprawl and little public transit meaning you will almost certainly want a car at the end of your trip and at that point, just drive, they are all like a 3-5 hour drive anyways which isn't bad (interstate traffic isn't bad outside of cities). The older east coast cities make some sense at least since they tend to have some trains and density due to historical past but they mostly already have rail lines you can take (albeit not high speed).
