> How would you alternatively design a system that calls emergency services in a crash?

If you want to prevent false positives—then, same as you’ve described, but only enable when either:

- phone is connected to Carplay via USB or bluetooth

- phone is connected to a bluetooth device known to be an auto (inferred by manufacturer ID, and configurable in bluetooth settings)

- GPS data for the last 5 minutes indicate you’re driving

And display an indicator on lockscreen that shows this feature is enabled.

Of course, consider that the downside of false positives don’t affect consumers or manufacturers—rather, they affect public utilities. Then, it’s easy to understand why this happens.
