musical motorways ...
"In the Netherlands, the local government decided to replace rumble strips outside of a village with musical strips. Officials chose the regional anthem, and if you see video of cars driving over it, the melody is quite clear. The problem with this innovation is that people who lived in the area hated it, so they begged the government to get rid of the musical strip, which it did.

We have two musical roads in the United States. The first is located on a strip of historic Route 66, situated east of Albuquerque, New Mexico on the way to the mountain town Tijeras. If drivers go 45 mph they’re treated to America the Beautiful, something that seems fitting for such an iconic road."
