reCAPTCHA is horrible. I am almost certain that some tests are intentionally marked as failed even if they are correct, simply so they can get more training in. And if you take any anonymizing measures, reCAPTCHA makes much of the web nigh impossible to use.
It's easily the worst UX I encounter online. I can't describe the relief I feel when I come across a "normal" CAPTCHA. It's coming to the point that if I could pay a few cents to outsource every reCAPTCHA, I gladly would simply to avoid this atrocity.
The tests are often poorly defined. I've been caught in reCAPTCHA hell a few times (but not recently), and it's often the case that I'm guessing... is this a bus? I'm not sure.
It's interesting to find out that this might have nothing to do with my ability or inability to recognize objects in blurry photos.
