In the list of many "but are you

A calibrated odometer, with accuracy of +/- X%? But what if the tires were changed and the odometer was not re-calibrated? And how diligent and precise were the operators that day? For example, if the mile marker's precise position was at an off-ramp, the operators felt it was unsafe to put the marker there, and so they planted it a few hundred feet later.
All these factors and more suggest mile markers
might be just a "pert near" reference for traffic accidents, as opposed to a precise measure of distance.
I don't know what the answer is. I've done zero research to learn it. I'm just saying that we might
assume, "well, of course they're accurate", when they might not be. Just like with an odometer. Just like assuming that a speedometer and odometer must agree with each other when this forum reveals they don't necessarily. Caveat emptor.
