I was driving to work the other day, when I started to get a rear alert from the V1 on K band. Since I have never come across a LEO using K in my area, I didn't think much of it. I came upon a red light, and then the signal grew and grew and grew. Finally it pegged the V1, full alert, and noticed what I believe to be a RadioShack detector on the windshield of the truck next to me.
I never knew that leaky detectors would leak that bad.
