What this game really needs is a Bulldozer with 500 Horsepower to allow you to flatten roads. This hand raking is getting a bit overwhelming for miles of medieval dirt roads. I am a little ok with the disparity in the concept.
But I do like the idea of a hauling cart but not sure what you would need it for?
I figured you could haul supplies from each of the locations or haul people in it. Could create some awesome in game trading as well
