Have you considered that you may be a bot?

I’ve had a Captcha that required an image like this one to be classified as a bike

Ceci n'est pas un vélo

I have a suspicion that it might depend on a few factors that might be related to Google’s ability to track, such as the browsers you use and whether you’re on VPN. I saw a post on Lemmy the other day (can’t remember where) that they suspect captcha is more annoying on Firefox, whereas fine with Chrominum-based browsers, esp Google Chrome. I think I sometimes experienced this as well, but I didn’t keep track.

I had one today where it was click on all the squares that contain a bus. One square very clearly contained a truck, not a bus. When I didn't select that square, it told me I was wrong.

They're so infuriating.

I’ve never in my life failed a captcha. Maybe you’re just bad at identifying bikes?

Very simple. You solve it too fast, it thinks you're a bot and you fail it. Click slowly and you will pass it every time.
