I am truly under the impression that car alarms serve no purpose. No one pays attention to them, and they do nothing to stop a potential car thief (unless it has one of those nifty ignition disabling alarms). I heard three alarms this morning and I didn’t even budge, just became annoyed as the sound went on and on.
With OnStar being installed in more new vehicles it is just a matter of time before it is used to alert authorities as to when a car is being stolen. I just wonder how much the fee is going to be for “false” alarms…
