Another “only in Japan” moment brought to you by Hot Air. In this one, the road plays music. The “melody road” has ridges spaced at intervals so your tires play a song if you drive at the right speed, which is 28 mph. Too fast, and you either get the song in speed mode or it’s a mush. Too slow and its pitch drops until you get woozy. Even at the right speed it’s hard to dance to, but it beats getting a ticket. To me, it sounds a little like a mosquito playing a kazoo.
