asphalt vs concrete roads are a good example. of course, if you want maintain stuff under the roads, concrete is a real bear.

And when concrete roads fall into disrepair, they get to be really nasty to drive on. I feel like I'm going to shake my car apart driving on some roads in Iowa.

I can't say that asphalt roads in disrepair are much better, but potholes tend to be more quickly fixed than slightly mis-aligned sections of concrete roads.
