why not

Other automated lines do (or don't whichever way you look at it!)

Good luck trying to evacuate a stranded tube train with no staff on board.
Fully automated metro systems - and the DLR - ALL have walkways in the tunnels
alongside the track so the doors can be opened remotely and the passengers
can just walk to the nearest station. Try doing that with the 6 inch gap
between the doors and the tunnel walls on the deep level tube lines. Oh,
and there's a 4th rail in the middle of the track so its bloody tricky to
walk along without getting electrocuted if someone hasn't switched the power
off.

All true, and DLR trains aren't unmanned or fully automated anyway. The
operator still closes the doors, after looking down the platform.
