Units are a known limitation of this process, because the actual physical units are present nowhere in the data we extract from Google Maps, and I was unable to figure out the inconsistency across various captures.

One solution is to measure a known distance both in Blender (distance_blender) and on the map (distance_physical) then compute scale = distance_physical / distance_blender and finally scale the whole scene by scale. Pro-tip Once you start a scaling operation with the 'S' key, you can directly input an exact scaling value using the keyboard.
