Hi Viz waistcoat Fair Play

Has anyone seen the Hi viz waistcoat with "Polite" on the back and with the black and white battenburg stripes? The reason being is this...why not? I myself would not buy one because I have an ordinary one and don't want to be stopped by an old woman to get a cat out of a tree.. However if it saves lives and makes you safe ...do it. I have read many people slagging others off saying they want to be Police..well if it saves that persons life so they can get home to little Johnny and its been proven to work.
I myself wear a delightful little number and ride a Trophy the size of the Ark Royal .... peace Y'al
