Will there be a difference between a self driving 1-5 person machine and a self driving 5-1000 person machine? A robotaxi can take you to the local robobus hub, which drives you to the local robotrain point, whereupon a Just In Time (un)scheduled train will leave, as all journeys can be coordinated.
