Just discovered that all these new detectors for automatic braking and parking in autos put out ultrasonic power of 100 Db. That's LOUD. We can't hear it, but as I remember we can "feel" it and It makes people uneasy and irritated. A friend irradiated some chicken eggs with audible music and those that hatched were deformed. Will these new cars spark increased road rage, pedestrian misbehavior, and birth defects?
