Unable to answer "How many car lanes does this road have?" – Calle Urano (Residential Road) – https://osm.org/way/62197062 via StreetComplete 58.2:

Only appears to be one lane but I believe is two way as there is one sign facing in both directions. There is on street parking which could be taking up the second lane.
