Not even just Apple products - in my 2022 Toyota, the car itself and my 4g connected dashcam both would call 911 on top of phone auto dialing. I’ll take the triple redundancy if it means the ambulance comes faster.
People who can afford to call 911 three times for the same incident should not get better service than those that call once.
Or they send 3 ambulances and then demand you pay for all 3...
Fun fact: often in the USA you don't get charged for an ambulance unless you use it. Call 911, let the paramedics check you over, and refuse to go with them. You just got a free health check-up -- a nice trick for the elderly
