At best this would be just trigger another arms race with people developing bots to trigger a series of "human-like" mouse events, which I'd imagine is a far-simpler problem than OCR.

Not to mention that it could only be used as a heuristic and not a test; so, eventually the weight of that heuristic will just be reduced to zero once someone publishes humanlike_mouse_driver.js with carefully-tuned-to-look-statistically-human mouse interactions available out of the box.

You know a peculiar thing that humans do? They do things slowly. You know what bot (programmers) hate doing? Doing things slowly. When you've got bots that are diving through thousands of registration forms per minute, and suddenly you need to slow them down to 15 seconds per form, well, that's already an enormous win for the site owners, even if it makes the new captcha fail (if the quoted statistic of 99.8% of captchas being solvable by bots is correct).
