Removing or alternating passing/overtaking possibilities on undivided rural highways, together with the introduction of narrow-profile guard rails between the center lines is a technique that was pioneered very successfully by Sweden and has now been used with similar success in New Zealand. And there’s definitely both the scope and the need to use it in the USA, too.
Some people think it is wrong to make the following comparison so I will apologize now to anyone who is offended, but the ongoing situation is so pointless and so crucial to the well-being of Americans that I hope you will forgive me for doing so:
“September 11, 2017, will be the 16th anniversary of the evil attacks on four planes, the World Trade Center, and the Pentagon, but did you know that for every single person killed on that truly awful day, over 200 people have since been killed on America’s roads? Yes, a total of almost two-thirds of a million people slaughtered in U.S. highway crashes, plus around 40 million injured, in just 16 years. And almost all Americans, including supposedly responsible politicians, completely ignore this hideous and unnecessary travesty because what?” Eddie Wren, Advanced Drivers of North America, Inc. — July 13, 2017.
