Went through a speed camera today on the A1 at 75 MPH. It was one of the Gatso type and it double flashed at me. I was deffo only doing 75 MPH. I thought the cameras are set on the basis of a 10% + 2 MPH tolerance. ie.30 MPH limit = 35 MPH or over (actual speed) or 70 MPH = 79 MPH (actual speed) or above you would get a ticket. Also does the cars speedo read a little over? I drive through that camera at the same speed every day and its never flashed me before. What do you guys think.
