Not good. Not good at all.
I've had questions about some of the UHP possibly using QT before. I've had conversation with one that doesn't follow "proper tracking protocol" when sitting in the median on I-70 and very much sounded like he was QT'ing folks to avoid letting on any radar detector users know that he runs a tough chunk of interstate.
I followed one yesterday for about 5 miles going down kind of a twisty turning canyon. I got two Ka hits with the Redline early on and then nothing for the next 2 or 3 miles and a dozen cars........OK, I figure he's not on the button anymore....... And then wham, he flips a b!tch and lights up some guy in a Eclipse hauling some major azz.
Did he radar him?? I don't know, but it worries me that he was radaring the entire time and the Redline sat deaf waiting for the 1-5 second threshold.
