Over the halloween weekend, I was involved in a 3 way car collision (everyone was okay) but before I could even collect myself and be able to reach out to my family - this feature had sent out an alert to my mother (who was listed as my emergency contact) who was notified of my car accident and had my location even though she was out of town at the moment and across the country - she was able to contact my brother to meet me before I can even realize what had happened. Never thought I would have to take advantage of this amazing new feature but seriously, check your settings and set it up.
