ok, but the point trying to be made is based on human's depth perception, but a car's basic limitation is the width of the vehicle, so there's missing information if you're trying to figure out if a car can use cameras to do what human eyes/brains do.
The width of your own vehicle is (pretty much) a constant, and trivial to know. Ford F150 is ~79.9 inches. Done. No sensors needed.
All the shit out there in the world is another story.
