I’ve become fearful of driving on washboard roads because of some calculations I have made. If point A is exactly one mile from point B as measured above the surface of a washboard road it has to be that if the surface of the washboard road from point A to point B is measured it must be longer than the “above the surface” distance. If we assume that the up and downs of the washboard road add ten percent to the one mile from Point A to point B above the surface we find that the “surface” road is 528 feet longer than the “above the surface” distance. If I’m operating a vehicle with perfect shock absorbers (for the sake of this argument) the distance from point A to be point B will be for me 5280 feet. In the meantime, the wheels of my vehicle will be traveling 5280 feet plus 528 feet for a total distance of 5808 feet. Since I’m traveling at the same speed as the wheels of my vehicle it means that I will arrive at point B before the wheels of my vehicle arrive at point B. This is a risk I’m not willing to take.
