a few years ago a friend of mine was on the highway riding his Helix. He said he was doing 70. the speed limit was 55.
a cop hit the siren and parked behind him on the shoulder. cop walks up, pauses, and sez "what, this is a motorscooter!"
the cop then tells my friend that the radar gun clocked him at 70 and goes on to say it has to have read him wrong. cop tells my friend to just go on and be sure to ride safely.
