> You mean the trains that go by once every 15+ minutes, and are confined to a track with no way for the operator to do anything but brake or speed up, compared to every few seconds with the ability for the driver to take control at any moment?

Yup, those trains! They'd have a shorter and more irregular schedule, but autonomous convoys would behave pretty similarly to that. Outside of emergencies like drivers assuming control to swerve into pedestrians, I guess.

Plus, like you say, no need to remove any of the infrastructure of really safety assumptions of today, just augment.
