I imagine the amount of bodies of water with cars clearly visible from space but not shore is too small to make it worth investigating.

FYI most of Google's "satellite view" images aren't actually taken from space but by airplanes.

  That's actually an amazing fact I'd never heard before. I would love to read more about that operation.

    I see them in my area on flightradar24, running very consistent grids like this one: https://www.flightradar24.com/blog/wp-content/uploads/2015/05/Pattern-Cover-1170x429.jpg https://www.flightradar24.com/blog/wp-content/uploads/2015/0...

  That's where Microsoft's old TerraServer got their stuff, too, IIRC, which is the first place I remember seeing anything like that online. Wasn't that much worse than Google's version, really, considering how much earlier it was. I think my parents had an aerial photo of their land a few years before even TerraServer was came around, from some guy who'd flown over a big chunk of territory taking photos and then sold them to the land owners. I assume this was far from the only person doing that, all over the US. Pretty cool back then, when a clear shot from the air of the area you lived in wasn't something you could grab at a computer any time you wanted, or with a cheapish drone and a few spare minutes. And before everyone else could creep on your space in the same manner on a whim, for that matter.

  Neat, I learned something today. I guess I just assumed it was all satellites.

  I don't know if "most" is totally accurate, but definitely the highest resolution ones and probably the most recent ones. Probably anything less than 1m. There is a significant discrepancy between the imagery viewable in 3D mode and the stuff that's only 2D, because Google simultaneously captures high resolution aerial photography and Lidar, particularly around cities. You can see vast differences in urban or rural landscape sometimes because the stuff you see in Google maps can be taken as far as years apart from the 3D aerial stuff. For example, you can see where the data source and rendering method change just outside the city of Winnipeg on the South end. Probably testable in many other cities simply by seitching between google maps and google earth.
