I was doing 60 in the 45 zone, two lane traffic, I'm in the left lane. I was just following the guy in the right lane about 2-3 cars ahead of me doing the same 60 - he got pulled over. The cop had a handheld device and was measuring from the right shoulder. Not to mention that I know this trap - I was thinking about something else.
I was VERY LUCKY since the cops here like to have a company of 2-3 people so they can catch all of speeding vehilces in such situations.
Bottom line - even thought the gun was most likely instant on, my radar detector was dead silent.
Usually it gives amazingly distant readings (we are in rural area here).
