If you take the subway pretty often (like me) you’ve probably noticed. Most people never take the stairs, unless there’s something wrong with the escalator. Also, everyone knows using the stairs is healthier.
So Volkswagen installed a piano in the stairs of the metro and a camera to see if people started using the stairs more.
I like the idea and i would probably spend some time playing in the stair if i came across this thing on the subway, but i’m not sure the neighbours will like to hear the piano all the time.
