Who's safety though? The car owner that chooses to not have this system? The other driver that can choose whether or not to have such a system? The inanimate infrastructure that was involved in the accident?

You can have a car make an emergency automated call without having the car company, their partners, and the government inserted 3 feet up your rectum tracking everything everywhere.

I just want to point out that in order to call emergency services on mobile networks you don't need a sim card nor a modem or writing telemetry on the nand so often and so much that it bricks the car within a few years
