Tesla could call it Egre-MuzzFlorp and it wouldn’t matter. The surveys showing people think “autopilot” means “can drive itself” were fatally flawed, in that they were done with non-Tesla owners.
Have your insurance company harass Tesla. Chances are they’ll come back with a report saying “driver depressing accelerator 13.42° at time of incident overriding AEB and ignoring FCW for 5 seconds”. That’s usually how these kinds of stories end.
In either case, you can put them in a deep sleep that uses minuscule amounts of energy and can wake back up on a timer. I’d start there.
