Nor do I.
My car alarm saved my car from being broken into and nobody had to call the police. When the alarm went off, the thief ran away. It's as simple as that.
How do I know I was saved? Because once I adjusted the sensitivity properly, my alarm didn't go off falsely. I would know if the alarm had gone off when I was out of earshot.
It saved me from being ripped off twice (2 real alarms in 7 years and no false ones). Both times the thieves ran away. The first time, I ran after their car trying to get their license plate.
bad idea - alarms do deter thieves.
IME, car alarms used to be a problem, but except for the rare 15 year old beater with an old alarm still on the roads, you don't here false alarms anymore.
It is rare enough these days that when a car alarm goes off I do look to see which piece of poo car it's going off on.
With 1 exception in recent memory, it has always been an older car. The 1 exception was a Ford Escape (IIRC) that obviously had a problem with the alarm. I could see the lady had her keys and could turn off the alarm, but each time she tried to back out of her space, it would go off.
It took her 5-10 minutes, but she finally managed to leave - I found the whole episode kind of funny.
