Is my speedometer right, or is the speed checker thingy on the highway right?
When you come back into town on the highway, the speed limit drops to 55 mph, and they have a speed checker on the side of the highway that lights up and tells you how fast you’re going. The speed check consistently shows me as going 5 mph less than my speedometer. I’ve passed it a thousand times, always checking to see if other cars are around to trip it. I’ve passed it all alone, lots. So, which is right?
