Technology for its own sake?

The obvious solution seems to be individual doors which
check that there is a platform adjacent before opening.
Something along the lines of a transponder at the start
of each platform which is detected by each door and
enables the doors on the appropriate side, and another
one at the end of each platform which disables each door.
Some complications for platforms on reversible lines
Ware springs to mind, and most termini. That sounds high-tech enough
to break down a lot, and requires fitting of kit at stations, which
are the most easily vandalised part of the railway. I was thinking of
a projecting metal arm under each train door which prods the platform.
Is it too easy to simply extend the platform?
