Today I was traveling behind a car at 34 MPH in a 35 MPH zone and we passed a mobile speed display radar . Approaching the radar the displayed speed was 34 MPH but right when I got in front of it the speed jumped at 50 MPH , it flashed me and went down at 34 again . Did anyone else got a ticket with the wrong speed from a mobile speedcam ? Do you know if all of them are taking two pictures so that the traveled distance can be measured in court and how hard is it to prove that ? Did anyone successfully contested a speedcam or should I just resign and pay the ticket , the extra insurance and save the money that a process would cost ?
