What you write is relevant to the price of oil, which is a tangent from what we were talking about, namely, ensuring a supply of oil in chaotic circumstances, e.g., closure of the Strait of Hormuz, which is itself a tangent from the original topic of Amtrak versus highways (since as GGGP already pointed out, Amtrak runs on oil, too).
But OK, let's talk about price. There's probably a 100 years worth of 'tight' oil just in Texas that can be produced for the price oil currently sells for. In other words, the cost of fracking that oil has decreased a lot. (And that oil is easier to refine than the stuff that comes from Saudi Arabia.)
