Every year at work some guys go to le mans, and last year one of the engineers had just got a fancey evo, brand new thing, and 4 up they saw 170 on the speedo in france. Dunno how accurate that is but its tramming some for sure. Shortly after that he got caught speeding at about 120 and the french po took his liscence off him and wouldnt let anyone go till they got 500 euros in cash.
