I'd like to see California consider reducing the total mileage of roads and focus on having a smaller amount of higher quality paved surfaces. My neighborhood street does not need to be 60ft wide, and our freeways do not need more lanes.
I imagine that all states would have more trouble managing more roads than they currently do, and less trouble managing fewer roads than they currently do.
Start with the fire department. They are the ones demanding 60 ft wide residential streets so that their trucks can turn around without having to drive a few blocks out of the way.
