If there’s no power, you still need to be able to get in or out of the car. It doesn’t matter if the 12V or the HV electronics are failed: you cannot leave somebody with only breaking a window as the method of ingress or egress from a physically intact vehicle. It is genuinely mystifying.

There's a mechanical door handle on the interior.

If you run out of batteries completely and need to get in the procedure is:

1. Open a small panel on the front and apply 12V to the emergency cables to unlock the frunk (this only works if the car is powered off as I understand)

2. Jumpstart the car's low voltage battery, located under a panel under the frunk

3. Unlock and open the door normally

4. Attach an EVSE charger to get the HV back online as well
