Ahh melody roads, what a delight. By using small grooves cut into the road at specific intervals a Japanese company is using your car to play melodies. The grooves make the car vibrate at various frequencies which can play out a tune if you’re driving at the ride speed (hopefully the speed limit). Too fast or too slow and the music’s either in fast forward, or is chopped and screwed. Sounds great, though it would suck if your daily commute included a song you hated.
