I do believe in them. we have some, surprisingly, in the parking garage of my apartment complex, you will see healights, or a car, or hear a car coming up towards you or behind you, then nothing at all. the garage is poorly designed and it only big enough for 1.5 cars to drive in it even though you have cars coming both ways, a real pain in the butt.
