Virtual routes can/should be developed to enable self-driving. Anything that can be reliably followed as a "track" by "computer vision" would work. Compared to a trains, the infrastructure investment would be negligible to install on major interstates. Cars that currently have cruise control with emergency stopping capabilities could utilize the "tracks" with minimal modifications. Confidence in your safety while being distracted and commuting is the value-add to transportation of Amtrak, and that could be replaced. However, Amtrak has historically been a socialism that blue-collar towns are OK with participating in, so my guess is that this initiative has more to do with giving government money to those people than solving any real transportation issue.
