Happens already. CIS will blank on some platforms about 2 minutes before departure and mindless fools run, jump, throw things, jam prams, arms, bags, pry the doors apart etc. as doors close even with the hustle alarm warning the doors are about to close.
@coppercapped. The system does have some merit but I am always concerned when comparisons are made. The UK rail network is a very different jungle and its wild denizens are a different breed altogether. Some of the things you mentioned are worthy of debate.
ASLEF are pro technology. I have no idea why systems like this are not pushed when it comes to new units. Seimens are a German company. Who makes those units you mentioned ?
There are external loudspeakers at each door and passengers are warned to stand clear as the door buttons are being de-activated. But, being an S-Bahn, most passengers are regulars and know that the doors shut automatically - in fact in winter it's necessary as it can get
really cold and snowy. The point is that the passengers can re-open them by pressing the door button - it's not that the driver or guard are closing the doors in front of you - so the pressures aren't so great. As I said, when the driver de-activates the door buttons only then is it not possible to re-open the doors - but the driver does not actively control the door closure.
The service through the 'Stammstrecke' through Munich city centre in the peak periods is 30 trains per hour in each direction - so the system works not only in intensive traffic but also out at the ends of the branches with a train every 20 minutes. And I am not sure that the people are that different - they all just want to get home at the end of the day!
The platform CIS does, or at least used to, blank as the train was about to leave, but as the destination is permanently displayed on the side of the train I don't think it was blanked to discourage people trying to get on in the last seconds.
The Baureihe 423 was built between 1998 and 2007, initially for the S-Bahn in Munich, but is now also used on the S-Bahnen in Frankfurt, Stuttgart und Köln. 462 units were built by a consortium of Adtranz/Bombardier, Alstom/Linke Hoffmann Busch and ABB.

Well here's a couple of hilarious reasons for you. Are we still holding the driver responsible for the doors closing on someone who misuses the door, train or platform and gets injured or killed? Fine if we trust the technology absolutely, far from if we don't. No CCTV or mirror implies every platform is similar, has no big gaps, that there are no curved platforms, that the passengers can be trusted and the railway company can be trusted not to blame its staff if something goes wrong.
The system I described is for use on S-Bahnen so, yes, the stations are similar, but by no means are all the platforms straight, my old local station of Westkreuz was an island platform on a curve. Trains can be one, two or three units long, the stopping places are indicated on the platforms and the CIS shows how long the approaching train will be.
Apart from the largest stations in the city centre they are not manned - and only recently has there been any CCTV coverage anywhere - because of their history Germans are very, very sensitive about being watched or spied on. CCTV is, in general, socially unacceptable.
