Or thats what Im led to believe anyway. We came across some of those "Your Speed is ..." digital billboard things and decided to see what sort of numbers we could bring up. After the first pass, did a u-ie to try again, going past the 2nd sign I didnt notice it so was pretty down that I didnt get to gun it properly. But was even more down when I saw red in my left mirror and blue in my right. Got let off with a warning Goes to show there can be some decent ones too !
