People hate CAPTCHAs because of this. You start to wonder if Google is actually lying about their AI capabilites and instead using YOUR responses to train their self-driving vehicle software, because it's always challenges that want to act like computer-assisted vision augmented "object recognition" machine learning input data relevant to driving, highways, public streets, byways and the department of motor vehicles.
... It's doing this by turning the CAPTCHA system into a multiple handshake system that statistically verifies and "triangulates you" so that once you finish their challenges, they know with 100% certainty what your IP is...
its literally on their website
You have no idea how the internet works. do you?
Lol right?
