@movq@www.uninformativ.de Hehe. :-) This steep footpath connects a hiking parking lot outside the village and the edge of the village in a fairly straight line. Garden owners are allowed to drive their vehicles down from the village to their lots on this pathway and up again. These two poles are placed about a third up from the botton on a short, comparatively flat section to stop people from taking this shortcut to get down to the country road. Said road goes through the village but there are hairpins getting up and down. The road markings have been added recentlyish. I suspect to warn shooting down cyclists of the danger ahead. I haven’t seen something like this anywhere else either. :-)

There are the two poles: https://www.openstreetmap.org/directions?from=48.735473%2C9.718418
