It says in the docs:

"## Accessibility

For users with accessibility needs who cannot use hand gestures to complete the challenge, reCAPTCHA continues to provide visual and audio challenges, and develop more accessible and secure alternatives."

So it seems you can just do a different task if you don’t want to do the hand thing anyway.

Edit: obligatory F google still of course.

Honestly oats are one of my favorite foods though, I have binge eaten massive quantities of them before. I think I may have been a horse in a former life.
