I was driving in today and spotted a LEO about a half mile away in the median, so I immediately dropped below the limit. As I went by, I saw he was using a laser on traffic. My Escort 8500 never made a peep. Then a bit later I was driving by one of those "Your speed is" signs and it correctly registered my speed. Again, nothing from the Escort. I turned the Escort off and back on and drove around the block to the sign again. This time it alerted.
Still, my confidence is shaken now. Is this an indicator it's on its way out? Or just a fluke occurrence?
