Now the Hokkaido Industrial Research Institute has gone a step further, with grooved sections of road that boom a melody up through your car. The grooves are a few millimetres deep and 6-12 mm wide; unsurprisingly, the closer they're grouped together the higher the pitch of the note produced.
They're planning to use different melodies for different areas, picking songs that have some association to the locale.
