Sorry, but this change isn't correct, there's SSV 5.01 (Distanztafel) below SSV 2.02 (Einfahrt verboten), so the oneway starts at Beustweg. Second, the bollard has an implicit default, so the highway doesn't need splitting for (incorrect) restrictions. In fact the only missing tag is a mofa=yes (SSV 4.09: Sackgasse, ausser Velo/Mofa).

Fixed with CS 135617177.
