If done well, this should fix the most critical gap in public transit. You can move massive amounts of people via trains and buses -- but that doesn't get them from transit to home (unless you're lucky enough to live near an access point).
The robotaxis should be solely used for that 'last mile' -- reduce the need for transit parking (which is insane for commuter lots).
This is what happens when you move a bus stop: https://www.irishtimes.com/ireland/dublin/2024/03/18/legal-a...
More seriously, bicycles exist.
There is no "gap in public transit". Transporting people in cities is a solved problem. It's trains+trams/buses+bicycles. There, done.
Sometimes you're carrying lots of stuff. Sometimes the weather's bad and you just don't feel like walking in it. All sorts of reasons.
If public transport and bikes haven't done away with cars in Germany, then it's not going to happen anywhere.
