It is not proper pointclouds, but it is the data used by Street view to highlight if you are looking at a wall, or at a street. It is also used for transitions between one scene to another.
You can see it is very basic 90deg angle geometry, instead of actual pointclouds. Still pretty cool!

Oh yeah, I didn't mean to come off as judgemental or nitpicky. This is fantastic work! And this data can actually be pretty useful, let's say if somebody wanted to build a racing game based on street view, using the boundaries of the street for collisions etc. Too many fun possibilities!
Someone used it years ago to make a neat visualization where they rendered the Street View imagery as normal and then used the same 3D data to overlay foliage and create an apocalyptic environment. Seems to be gone now but there are some articles about it like this one: https://www.citylab.com/life/2014/03/epic-google-street-view...
