Engineers in Japan have constructed roads that play music as you drive over them. Grooves cut at specific intervals vibrate your tires at a specific frequency. Driving over them strings these notes together, creating a song. According to The Guardian, patent documents describe the technique as “formed in a road surface so as to play a desired melody without producing simple sound or rhythm and reproduce melody-like tones.”
A researcher apparently came up with the method after driving over a section of road he’d earlier damaged with a bulldozer. So far, there are three different sections of melody road in central and northern Japan, one of which plays a well-known pop song. The music sounds best at about 28mph, so we’re guessing going fast makes it sound like you’re running over Alvin, Simon and Theodore. A video of the road in action follows the jump.
