Quality of roads in a city/town typically correlate with the income and socioeconomic status of the location. In the Bay area, affluent suburban areas have pretty good roads (believe taxes have an effect). While cities like Oakland, Vallejo, Richmond have streets full of potholes and very bumpy roads that can even damage your car while driving at a normal speed. For state with the highest income tax wonder where the funds go to. Good article on current state of US roads. I've seen other countries in EU and they seem to have much better or comparable roads in rural areas than the US.
