Level 2 demonstrates an annoyance I have with such captachas. It states to select all squares containing a stop sign. It becomes some sort of game theory around what I think other people think a stop sign "is". I would consider all parts of the stop sign, including its metal stand, part of the sign. Other people apparently think only the top bit, the red bit, of the stop sign "is" the stop sign.

If I'm supposed to select all squares "containing a motorcycle", and one square contains just a couple pixels of the edge of it, would other people select that square or not? I would, since it contains pixels of a motorcycle, but apparently, again, most people disagree with me, because I'll get it wrong if I do that.

It just drives me crazy having to choose what I think other people would choose, rather than choosing what I believe is objectively "correct". Maybe you could argue that's part of the test, to know what other humans would choose. But I don't think that was the original intent/design. I'm constantly second guessing myself on these types of captchas, and constantly getting them wrong.

If you bolted the metal red octagon to the side of a building (such as in a very dense urban street), would it still be a stop sign?

		It might not be a government-enforced thing but there isn’t much reason to go to the effort of putting a red metal octagon somewhere if it didn’t mean stop, in some way. The things don’t just fall of trees and land on the side of buildings.

You seem to gave a very outside view of humanity, are you sure you are not a robot? Perhaps some edge case.

You're assuming that that type of captcha is about selecting the correct squares rather about how you select those squares.

Even before the current "AI" craze, selecting stop signs was a trivial problem for computer vision - especially when you're OK with sub-100% pass rates.

> all squares "containing a motorcycle",

How about feeling trapped because no square contains a motorcycle. For example, a motorcycle wheel is not a motorcycle.

It definitely feels more like a game about guessing common interpretation than anything else.

If you are lucky you might get an image that hasn't yet been shown to enough people for the system to learn the "correct" answer, in which case you get a free pass submitting even blatantly incorrect solution.
