Looks just like a map of housing prices in the US. Makes sense, because when housing gets too expensive, people are forced to live farther away. Which leads to longer commute distances.
What a great idea! In the US, we waste a lot of money by paving shoulders, which sit unused most of the time. But the Germans have eliminated the need for a shoulder by having each lane donate half of its space in the middle. Simple and effective.
