I knew that our low-tax attitude is shifting costs to auto repairs, but I didn't really know how big the problem was until I read "Lousy Roads Cost your $335 Annually", Wired, accessed 2010-04-28.
The $335 is average across the country; in some cities the average can be $750. And that is just for repairs to cars. The article also describes how road repairs get lower priority than new construction. New construction is also generally done with bonds, and so that means we have to consider interest costs. Talk about saddling future generations with debt!
There may be hope. One federal bill is proposing that more money go into repair instead of new construction.
