The real question is whether the acknowledgment sound should be Zugbeeinflussung or Aufzugbeeinflussung.
Does it have something to do with Talent 2 (cockpit display) at the beginning of the video/streaming?
Why stop at elevators? Put it in cars too, imagine the chaos it would cause... MWAHAHAHA! PS. Don't forget the SIFASIFASIFA.
Forget elevators, I want PZB in airplanes! Dont forget to release PZB if you wanna go faster than 45kmh, and press the acknowledge button whenever you bump into clouds!
Don’t forget putting it in British and American trains. Oh and all other countries while your at it
