> Mercedes calling their call center seems a bit aggressive
through necessary: I mean, let's be honest under which "normal" conditions do you ignore the warning system _and continue to do so even after the car stopped_?
Whatever it is if you are not a journalist testing something out there is a pretty high chance you need help one way or another.
So they call you to then figure out if they need to call you an ambulance (e.g. imagine you had a heart attack, or passed out due to some circulatory mall function) or a technician (the warning system malfunctioned) or well if they can safely ignore it (you are a journalist trying things out).
It's in a certain way just a natural extension of the existing emergency call system (common (required?) in the EU) where on detection a collisions/the airbag going off an emergency call is made. It just now detect a user seemingly becoming unable to interact with the system.
It might feel aggressive but it shouldn't trigger under in any normal usage situation and even if there might be some harmless situations it likely will save lives.
