X2 what murphy said. I was on my way home from work on my WideGlide in a 3 lane expressway. An unmarked light blue Charger was ~1/4 mi ahead of me in the center lane. 60 mph zone, everyone was driving 75, I was a little faster. I slowed to about 65, as I was suspicous of the Charger. I passed the Charger doing 65, he pulled behind me and lit up the lights behind his grille. He asked how fast I was going, I said 65 when I passed you. He reminded me it was a 60 zone, I said I was basically blending in with everyone else. He said "well, someone behind me was doing 81". I said "besides me, there was a car and pickup behind you." He said "yes, and one of you was doing 81, but I don't know which one". He went on to say that motorcycles are small targets for rear facing radar, and that I should slow down a little. I said "yes sir, I sure will". Didn't even write me a written warning, just verbal.
Laser is another story..........
On a side note, that Charger had really dark tint, no lights visible in rear window, no light bar, etc. Even had a civilian license plate instead of a city or state govt plate.
