For further (even more insane) evidence, you only need to look at where we've chosen to build our highways, oblivious to all obstacles, elements and mortal danger. A few of these offbeat avenues pass through mountains and at least one goes through the middle of a building. Then there's a European highway with a bridge that appears to have been inspired by a Dr. Seuss illustration, and an interchange in Asia that has a roller coaster-like design.
