The pavement has been scored with vibration strips so that when your tires roll over them, the vibration plays music. I drove there last weekend and it was a fun little gimmick. To find it on the map search for Musical road Lancaster CA.
Link follows. It’s supposed to be the William Tell Overture, or the theme song for the old TV show The Lone Ranger.
Nothing to do with the speedo. As long as you drive at any constant speed, it should sound right, just in a different key. But they screwed up (twice!), and Tom Scott explains why: Why California's musical road sounds terrible - YouTube
We were recently on a trip in SW Utah and I saw odd stripes in the left lane of a two lane highway. It dawned on me that it might be “musical” and I went over and it was. We only caught the tail-end and didn’t get a chance to go back. It was somewhere around St. George. Wish I could’ve done the whole thing as I think this is a cool concept.
It is the main road connecting the city of Kaposvár and the M7 motorway. The road was installed in memoriam of the lead singer of the band Republic, László Bódi aka Cipő.
Agreed. But I have another problem with some implementations. Some rumble strips can be seen on the right side of the lane so that only your right tires hit them and play the tune. If the driver wants to avoid the music they’d have to veer left and drive in the left part of the lane. From the videos it looks like this is possible. The problem I see is that this puts the driver in a greater risk and nearer to the oncoming traffic. Why not put the rumble strips on the left tire, so that to avoid them you’re nearer to the shoulder and thus safer?
