So what it is needed is that the car communicates with 911 and an automated system will tell it to wait for help, go to a destination where help will go to, or go to a help center (hospital or similar) where help will be waiting. It could even work if you are at home and have an emergency. Call 911 and if they decide you should go to a health center on your own it will send where to go to your car. Of course at first wait for help should be the default, but when automated driving improves, and the processing of emergencies improves too, an automated response system should be the norm for most of the time.
