Roads exist for me…mainly to furnish reasonably direct connections between cafés and chili parlors, taco wagons and beaneries, eat shacks and confectioneries, burger joints and frozen-custard stands, barbecue sheds and fish camps. In other words, roads are there to tie one reason for living to another.

Really. That does not give me good information like a comfier ride for cars or it gives cars a less chance of a tire being popped.
