Its only Google's ReCaptcha that sucks, with its eternal gaslighting.
"Select stairs": okay, does that mean the railing too? And probably some percentage of people clicked rails, so now I have meta it and guess if that percentage is enough to throw off my guess.
"Select motorbike": okay, but you're showing me a bicycle. I'll click "skip". FAIL. TRY AGAIN. Sighs.. okay, I guess the average person is so dim-witted they will misidentify a bicycle for a motorbike.
> "Select stairs"
And the "correct" pictures all shows steps, not stairs.
> "Select motorbike"
And the "correct" pictures all show mopeds, not motorbikes.
Christ, don't get me stated on taxis that aren't black, fire hydrants that aren't a yellow H sign (apparently I'm supposed to look for something like a yellow painted R2D2) and WTF is a "crosswalk" (a pedestrian crossing?).

That's not gaslighting.

No, there are multiple accepted answers.
It’s not just Google. Look at Arkose, which are not only difficult for humans to solve, they’re difficult for humans to even understand (“move the particle to the correct orbit”).
