I agree with the flexibility point 100%. On the cheaper I really do not know. Is pouring asphalt cheaper than putting rails? I honestly do not know. It also might depend on the implementation. I remember a history teacher mentioning that the uk built railwways providing time-limited exploitation licenses for private companies that built them (after x years they became public) and they built a vast network quickly . ( I found this pdf: https://www.campop.geog.cam.ac.uk/research/projects/transport/onlineatlas/railways.pdf https://www.campop.geog.cam.ac.uk/research/projects/transpor... about the expansion, but it does not mention the licenses) In the car case we need to also consider the "wagon", and the fuel cost is outsourced to the customers.
