” Surprisingly, the Autobahn is safer than U.S. highways.(a 28-inch-deep roadbed versus 11 inches in the U.S.) and better maintained”
Engineers build the US system for decades instead of centuries. This is the case for “overbuilding” infrastructure.

I’m certian the use of asphalt shingles and recycling them into roads will put a dent in energy consumption.
—use thick metal or tin roofs, design houses with a steeper pitch.
