Here is an example. The population of Colorado is largely urban. Virtually everyone lives along the Front Range. Geographically, the state is largely rural. The Denver metro area controls the state. State and federal highway money already primarily goes where the Denver area wants it to go: highways in their area and along the routes to the ski resorts. Without highways, the rural eastern and western parts of the state will cease to exist. It is a positive feedback cycle.
