Tonight I was out for a drive, and encountered my first rear laser alert.
I was in the right lane, and there was a Toyota Avalon behind me, but in the left lane. All of a sudden I get a laser alert, and there was no oncoming traffic at the time, but I looked in the mirror and see the Toyota. There was a car ahead of him and slightly ahead of me, so I figured the laser beam was reflecting off the car in front of us and into my detector, but that car turned off the road so it was just me and the Avalon, which was still behind me in the other lane. The alert went on continuously for about 7 or 8 seconds, until we went around a curve and the Toyota turned.
