Have you notice it doesn't matter if you're on road, the lawn, in mountain area or in a swamp... you run at the same speed !!!
Do we know if it something is supposed to be implemented later ? (sure FC has now bigger concerns).
Road should provide u a hugue speed bonus (even more when u have a car) while difficult ground should give u a malus (is it difficult to code??).
That would give to road much more importance, with like in the past, lot of activities around them (hehe, guess which one) : if u want more speed advantage, u might meet trouble (which oblige you to go back in the durty ground)
