Germany is thinking about automation, but for cost saving. (it might increase) but to be able to put more trains on one track and behind each other..

Yes, by always stopping in the same place, lines can be painted at entries and exits to speed up station flow.

If you want to erect barriers to increase safe station capacity, you need that too.

Finally, the automated trains will have smoother acceleration and braking, reducing wear and tear on the trains and tracks.
