I have been driving in passing lane my whole life and never been cited for anything even one time when I was going at 72 on max 55 limit . I saw a cop was driving right behind me from nowhere , I swiftly changed to middle lane and slowed down to around 55. I thought I was going to get citation that day and started cursing myself when he changed the lane as well with flashing light on but luckily it was for a truck which was behind him and got passed him from exit lane. Generally what I have observed in MA its ok to drive upto 10mph higher than limit like if its 55 then you can drive upto 65-70 . that's for highway though. I drive in left lane most of the time within that range and if some guy comes close from back I let him pass and come back to passing lane again. So it depends upon ur timing and ur luck too. if I were you I would file a hearing against the ticket and explain whole thing in court but like others said wont use that racial word directly.
