Hi Guys, Drove by a mobile speed camera with the dash potentially indicating up to 80 mph (the speed i never exceed in my car). My GPS tells me that 80 on the dash is 77 mph GPS. Do you think I will get an NIP in the post? I know the ACPO guidlines are prosecute at 79 and above, but I am worried the trigger happy police may decide to prosecute for below, like 77! If I do for going 77 in a 70, can I defend it in court? I have a Mini Cooper and it's annoying how the speedo is in increments of 20 MPH! Thanks for letting me know!
