>when my mother wound up in an accident, used Hey Siri to call us from her hospital bed when she couldn’t reach her phone.

I actually experienced this same thing last winter, and it was a life saver. I was taking out the trash and slipped on some ice on my deck. I hurt my back pretty bad and cracked some ribs. I wasn't able to shout to my wife inside because of the pain, and I wasn't able to stand up because of the pain. I was only wearing a pair of shorts because I wasn't planning on being out long, but the temperature was below freezing and the wind chill was below zero. I had no shirt or socks on and only a pair of slippers to protect my feet, so laying out there until my wife got suspicious and came to find me could have had some pretty bad consequences.

I didn't have my phone on me, but luckily I was wearing my watch and was within Bluetooth range of my phone. I was able to get Siri to call my wife and have her come out and help me back into the house. Kind of a nice feature.
