Yep. 0ft-1000ft AGL Takeoff, Climb, Approach, and Landing are the tough bits. The rest (Cruise) is very low demand and much easier than driving.

Taxiing is probably harder to automate than the rest. But you could have pilots on hand to taxi to the runway, and take a shuttle to the other end and hop on a just landed plane to taxi to the gate. Or you could use tugs for ground movement.

I'm not convinced - in a commercial airport taxiways are controlled by a ground control systems, not just pilots looking out the window. If the only airplanes around are also equips with the self taxi system they just report position to the central control and that tells them when to go. There needs to be emergency overrides for when that system fails, or a small plane without it is around, but that can be handled by stopping everyone else in the area until the hazard is gone.

Time will tell...
