The OnStar controller is hooked up to accelerometers that can detect a crash and initiate a call for help...even if you are unconscious.

Let's play the odds game. What percentage of cars have an accident? Of those, what percentage result in an unconscious driver, and no one to call for help? Of those, how many are head-on crashes? Remind me again, where is the battery located in these cars?

Logically, it would appear to me that in a crash harsh enough to do what you are claiming, the battery will be destroyed - all it has to do is get a crack and lose it's fluid - then it's nothing but lead and plastic - it's inert.

Now, if the On-Star unit has it's own power supply, built in and armored, you have a great point.

There are plenty of "slide off" and single car loss of control accidents in Idaho. "Head on" is pretty unusual with divided highways. Driving too fast around a turn or sliding off due to rain, ice or snow is fairly common. Multiple roll overs are common too. All of those can occur without damage to the battery. If you don't want the technology, don't buy a car with the equipment installed and/or don't pay the bill for the service.
