How good are American roads?

The SFBay I-880 and US-101 are always packed, often under construction, but still pothole-filled, with sections of extreme roughness. Compare this to our OR neighbors, where there are signs saying "your tax dollars at work" by ORDOT everywhere. I used to scoff at this as a display of insecurity, but apparently (from TFA at least), Oregonians' tax dollars _are_ at work.

CA takes so many tax dollars from my hands. Why aren't they "at work"?

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.

Oregon manages about 40% the road miles of California with 10% the population and 70% of the tax revenue per capita.

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.

I dont follow? Are you invoking some diseconomies of scale. California has about twice the roads but more than 5X the budget.
