Hello proprietario,
I moved the gate from the center of public way to the position of entrance in the private property because in the previous position it was impossible to route on the public way using OSM data.
Now passage on the private road is not possible, even for pedestrians, see https://www.openstreetmap.org/directions?engine=fossgis_valhalla_foot&route=42.86596%2C12.73779%3B42.86720%2C12.73690#map=17/42.86884/12.73650
