This isn't quite a fair comparison; many of those roads are running through areas with low land values. Comparing ground-level rail through cornfields in Oklahoma is apples and oranges to a busy, high-capacity subway underneath Manhattan.
For context, we have 4 million miles of road in the US. So even with $100m/mile, we're talking trillions of dollars before we even get to the actual feasibility of putting rail everywhere.
Rail is great, but there's no world where it does the same thing self-driving vehicles would.
