How good routing works for places like this depends on the routing engine: 2 of the 3 "standard" engines that are implemented on the OSM website are working correct here (see for example Graphhopper: https://www.openstreetmap.org/directions?engine=graphhopper_car&route=52.413117%2C13.421177%3B52.411267%2C13.416425#map=17/52.411634/13.418630).

But some routing engines unfortunately aren't considering driveways for the "last drive" and are therefore failing in cases like here. We can't change that in the OSM data. If you are aware of any routing engine that is failing here, you could consider reporting this issue to them (e.g. to the delivery companies).

But I added some fences around here, maybe it helps humans looking on maps if they see a closed fence between Weitbrucher Straße and Rathenower Straße #19-#21.
