Isn't it about time to declare car alarms a failed experiment and do away with them? They have long since degenerated into just another background noise of the urban landscape. When was the last time you heard a car alarm go off followed by someone running into the street, shouting, "you there, rapscallion, unhand that vehicle"? When was the last time you did? I can't remember either. When the neighbor's alarm wakes you up at night, is your first instinct to call Avocado Girl for help, or to curse your neighbor and several generations of his ancestors? Can you even tell your car alarm apart from your neighbors'? The other day I arrived at the grocery store just as a squall dropped a load of hail on the parking lot and was almost deafened by a hundred car alarms going off at once. I hate those things.
