DELAYED REACTION

Something I remember noticing at least a day or two ago and am only now getting around to commenting on: I heard a car alarm go off and thought to myself "Who still uses those damn things?" Seriously, who does this. Rather than believe it was being actively used for its intended purpose by its buyer, I choose to think that it must've been installed in the car many years ago, and the owner is simply too lazy to have it removed or disarmed or whatever. They don't still make cars with those things built in, right? Where on the face of this planet does that constitute an active deterrent rather than background annoyance?
