Speed limit is 45 and returns to 65. We are out of state and driving a dealership rental car. Rely exclusively on cruise control. Had cruise set for 47 mph and had not increased speed prior to speed limit change. Officer pulled us over still in 45 zone swearing we were doing 54 (increasing to get up to 65 early). No way to argue or deny it since you can’t see the radar etc. Officer kept insisting that he would t have pulled us over if his radar hadn’t picked it up. Course no mention of the vehicle traveling behind us that passed us before he turned around to follow.
