Unable to answer "How many car lanes does this road have?" – Wood Street (Secondary Road) – https://osm.org/way/54800519 via StreetComplete 59.3:

Photo taken from northwest corner of Forbes at Wood.  Wood is marked for two travel lanes south, one north however the second southbound land is also marked for parking.  I'm not sure would be appropriate to record for lane markings.
