According to https://www.uccle.be/sites/default/files/filemanager/Legal/Ordonnances/2022_09%2029_ODP_Gendarmes_Prolongation_5_U1180_fr_nl.pdf

The oneway street test was extended at least until 2023 and https://www.uccle.be/sites/default/files/filemanager/Com/Docu/2022_09_21_gendarmes-pistes-pour-nouveaux-tests_U1180_fr-1.pdf say that in 2023 or 2024 all the street will be oneway. No recent street level imagery is available ; so survey needed.
