Posted speed limit was 70, and I was somewhere in the extremities beyond that number. Michigan State Police running KA band sitting in the median toward the left side of the highway (closer to the northbound traffic lanes) as I headed south. I see him and brake and then my radar detector goes off 1 blip KA. Then as I drive by him, I get up to 2 blips when I am 10-20 feet away. However, as I drive behind him my blips go to full and keep trailing for near 1.5 miles.
Was he running rear radar only?
I suspected he was because I should have gotten full KA by the time I was 10-20 feet away, and he should have ticketed me. However, I guess he just sits there in the median facing southbound but using his rear to get northbound (and he is sitting in right next to northbounds fast lane) so he can pull out and ticket the northbound traffic easier.
