Smashing the glass, prying open trunks and doors isn't the focus of these systems.

Onstar didn't alert you because your car was never started, nor did it move during these break-ins. Imagine how inundated Onstar would be with false break-in notifications if they put a security system in every car that activated under every break-in scenario. It would get to the point that Onstar would ignore those notifications exactly the same way most people ignore the horns going off on a cars security system in a parking lot!
If you live in an area where your car is being broken into on a regular basis then you either need to a) move the car to a more secure location. Or b) Buy a security system that is customized to the type of break-ins you're experiencing. However, keep in mind that there's not a single security system that stops smash and grab break-ins. They'll just alert you long after the thief is gone...

That being said, your security system did work...you still have your car.

All of this!!!
