I was driving on the interstate the other day in a large city and traffic is stopped on the on-ramp. I have my V1 up as usual. I get a laser alert, but think nothing of it. I drive a few more car lengths up, and get another alert. This time I realize it isn't a TrailBlazer's rear lights. As traffic finally moves a bit more I get one more laser alert. I look up and I see the police officer with his laser gun pointed at the traffic on the on-ramp checking speed. The awesome thing is we weren't even moving, so he must have been getting a 0 reading.
Either way, I just wanted to share so that people know you really can pick up laser scatter with a V1. I was a few cars behind the first car that got hit, and I still picked it up. I'm sure it would have been different if we were actually moving; in that case it isn't likely I would have had enough warning.
