Always heard that due to restrictions in Europe speedos over here generally over tell your speed so you can generally do 10% over the speed limit without the fear of getting caught.
Had an old Citroen and this was true when I compared the speed on my GPS to my speedometer the GPS speed was way lower. However purchased a new car recently and now the speedo seems to be as accurate as my GPS so it got me thinking.
What kind of speed can you generally do over the PSL with an accurate speedometer (ture speed) in Ireland before getting pulled?
