Rumor has it that in California, some years back a man was written a ticket for Impeading traffic.. He was in fact doing the posted speed limit. (The judge dismissed it but with a stern warning to keep up with the flow)
Now I did not verify that.. The next story I have verified, in fact I am part of it.
At work one day I got a call (9-1-1) Complaining about one of my Troopers (Also named John) who was driving his marked patrol car at the posted speed limit.. Mre. Speeder wanna-be was complaining "he is going to cause an accident driving like that"... I transferred the caller to my Sgt. who then ask me which trooper it was (i already knew so I told him) and ask if he wanted me to relay any message... Perhaps "Good job".. he agreed and I did.
