I do realise. That by itself is worrysome. But now car manufacturers tie legallly required functions like the enmergency buttons with bloated platforms of "convenience" functions that users can not disable completely.

Correct me if I'm wrong, but I think I've read somewhere that it can be a SIM-less phone that abuses emergency call flow in 3GPP. GSM specs have special accomodations for 911/112 type calls that don't require a SIM(that sometimes ironically lead to normal calls working fine and just emergency calls failing).
