What counts as a truck? Is a fire engine a truck, is a 4x4 (like a Landrover), a HGV (ie lorry), a box van?
What counts as a bus? Is a coach a bus, a minibus?
What counts as a bicycle? Is a pedal-and-pop (a pedal cycle with an engine)? The image shows part of a headset that might be on a bike, is that enough to call it a bike, might be a lightweight motorbike?
Is a hovercraft a boat? Is a helicopter an aeroplane (according to the people setting the question)? Do pedestrian facing lights count as traffic lights?
Then every now and again they add in an image that is, I assume, purposefully obscured (uniform noise) as if painted by an impressionist and titled "boring city with smog as viewed by someone with cataracts, there might be half a bicycle wheel in somewhere".
One question that I apparently answered wrong for years as a German are the traffic lights. In English, traffic light seems to refer only to the assembly of two or three lights used to control the flow of traffic. The equivalent German word most commonly refers to the entire installation, including the pole, button (for pedestrians and visually impaired), speaker (for the visually impaired) etc.
So I selected much more than what Google expected me to select, I selected all the cables and poles as well.
I'm pretty glad that hCaptcha at least gives me an example of what it's looking for
This always throws me off, if it says 'Select all cars' for example and there is a car going into the next part for 10% but the main thing of that square is a tree or whatever, do I mark that? But I also always select the whole pole, no idea if it's right
My goal is not to optimize google's AI training, it's to get access to the damn website. I think part of what it does is compare your answer with other people's, if the AI is not sure, so it's more like a Keynesian beauty contest where I'm trying to guess which tiles the average person would pick.
(And fail and then have to go through 5 more screens of this.)
I live in US (though not born here) and truck and bike ones give me a bit of a pause too. The fact that bike is both a bicycle and a motorcycle doesn't exactly help either. And btw is scooter a bike?
My heuristic (which seems to be pretty accurate) is to accept anything that's vaguely related to the object that they ask for. eg. if they ask for "bicycles" and the picture has a motorcycle I select it.
Are these examples of captchas that have failed you or just questions that come to mind? I ask myself the same sorts of questions but then haven't actually had captchas fail me for it much.
Sometimes the turbine housing, or a section of a stabiliser aerofoil looks quite aeroplaney. But yes, I assume I've resolved that one correctly -- just getting in to the flow of my rant!
