Google Maps used to be really bad in my then neighborhood which had roads and garages underground and bike lanes and footpaths on the ground level.

For the longest time they didn't even have the numbers of individual houses and treated the whole area as an atomic blob :shrug: A neighbor put the numbers into OpenStreetMap eventually and soon after Google Maps had then too.

For a while they still treated it as a normal road though which means "find route" was still unusable but you could at least use it as a map. Nowadays they have separate entries for the above-ground paths and it works.
