For example, if a stop sign is on the same plane as the object that surrounds it, that's a strong signal that it is not a real stop sign but rather a projected or displayed one.
It's conceivable that in denser or older areas, signs are sometimes placed on structures because there isn't room for a pole.

Agreed. I didn't say it's definite, I said it's a strong signal. Even strong signals need to be weighed against other available data.
Apple Maps shows stop signs and traffic lights on the map. A database like that would be another strong signal, but also not always accurate.
True, but LIDAR should make that detection more robust.

That's much harder to detect with computer vision alone, especially if they're dealing with hackers who can test it with a real car and continually iterate on it to find different ways to trick it.
