The Two Futures of Driverless Cars

Here’s an idea. Rather than companies investing more in autonomous trucking they invest into railway systems and autonomous and perhaps electric trains. It’s an easier problem to solve and the general public would benefit tremendously from having more rail infrastructure. Rail is cheaper and more efficient than trucking and we could save money by trading expensive road and highway maintenance with rail maintenance. Also rail is an easier mode of transport to electrify than trucks so it will be more practical in that sense too.
Edit: also the public could benefit tremendously from expanded rail systems. Imagine being able to hop on a bullet train and in a matter of a few hours being in another city several states away. Sounds nice to me and again it can be electrified relatively simply.
