Here's a Fermi-ish question: given the fractal nature of typical landscape, should a truck driver budget for 10 times as much time as would be predicted by using the known typical speed of the truck and the distance as the crow flies?

(Aside: the nearest grocery store to my house is 1 mile away but the shortest route by car, as measured by the car odometer, is 10 miles.)
