Usually when they are going off in my neighborhood the car is streetparked and that's how they end up getting triggered (sometimes a loud motorcycle can even do it). So the owner could be like well over a 10 minute walk away and out of earshot anyhow. As a result most of the time when I hear a car alarm it rings until the thing shuts itself off automatically to save the car battery.
