Japan’s Melody Road
In northern Japan, they have carved specific grooves into the road to create a melody.
Here is a video of the effect here:
Melody roads? Really? That’s the best you can come up with that technology? Come on, even I can think of something better.
When I was a child, there were some birthday cards at the local odd lot store. The card came with a strip of plastic attached to it. If you ran your fingernail along the plastic strip, the grooves on it would sound out the words, “Happy Birthday!”
Why don’t we do that with the groove strips along the side of the road? Instead of “Happy Birthday,” they could say something useful like “Wake Up!”
