I'm abusing one government department due to suffering abuse from another. If that causes a different kind of staffing shortage - that's something I don't have control over, but has the same root cause as the DB incompetence.

In my case because I do have not mild but moderate autism and panic disorder, it would genuinely feel like a heart attack if that happened to me. I wouldn't be lying about my symptoms.

The problem with that is - why do I get access to this "out" by being able to call EMS to get off the train? (Provided you agree with me that I would be a valid call). Why does everyone else have to suffer?

My worldview is they don't. DB wants to take you past 15 stations? Here's a mechanism to stop them.

I'm agreeing it's an abuse of the system, but it's valid because it scales. If there was a flood of EMS calls every time DB skipped 15 stations - DB blinks first.

Maybe a better example from me would have been an emergency stop button?
