I'm trying to understand something about how power flows through Teslas: In the accident I recently had, the firefighters cut the 12V battery cable as per instructions. Although power to the console and Instrument Panel was gone, we were still able to activate the doors and the trunk. Some hours later I was still able to receive telemetry from the car (location and main battery state) from what I recall, but was unable to communicate with it by morning. So, what does cutting the 12V battery cable do? Seems to me that the car is essentially still powered, whether it's "ancillary" functions or more, I've got no clue.
