How would this work, as If i walk along the side of a dual carrageway the
data would say average speed 3.5mph. In contrast a car may say 70mph,
therefore the average speed of the road is about 37mph so incorrect, as on
foot I could have gone faster, but was limited by my own phisical abilities
rather than the road and its features.
