How does that differ from what happens today?
Eventually the driver presses the close button, and the doors close
anyway, possibly hitting people and trapping things as they do, and the
interlock only kicks in if something above a given size is trapped.
There is no way you would get that arrangement past a risk assessment
for a completely unstaffed system in the UK. It would have to work
like lift doors, where if blocked they reopen, and that would cause
massive delays.

Ahh, OK, I see what you meant.

OK, there are already dispatch staff, but they can't see well
enough to do it on their own, and they are only at busy stations at
busy times of day.

At really busy stations there are sometimes several dispatch staff so
that they really can see the whole length of the train. Same happens at
very busy NR stations.
