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.

I think my browsing habits may have changed, as I rarely see captchas. However, just the other day, my son was frustrated by one that he said had taken him fifteen or more tries, and he still hadn't succeeded.
