Some very good points Danno, and that all makes sense, what about in some case's , depts will test if you will new or purposed new markings, I say this because, Goodyear Pd for the good part of I want to say 12 years now have been white with a black/blue striping down the middle, but in the last say six months, they have two?, Tahoes, maybe more in B&W , its only Tahoes, none of the cars are in B&W yet, so that can mean a few things, either and or they are testing the new markings, or only doing the B&W on new PPV's the city gets.
