Okay, hear me out. Yesterday while on my journey to my school I had a pretty bad car accident. I recently bought a new Apple Watch SE. And after the car accident (fortunately the seat belts saved me) I was able to get out of the car. I noticed the watch ringing and indeed it was notifying me about the crash I just had. I canceled the SOS call though cuz I was able to do that myself. But yeah, I think this feature might be useful.
