Back Away! You Are Too Close to the Car!
And Other Notions for Car Alarms
Years ago, somewhere in the neighborhood, somebody had a car alarm that instead of blaring a klaxon call would speak in a really loud voice. I remember the first time I heard it I was astonished. I never did learn which car it was installed on or even if it was on more than one car, but I can assure you it always got my attention.
