I'm surprised, too. My solve rate (as a human) is <50% for reCAPTCHAs of the form "select all squares containing a motorcycle/bicycle".
Does anyone have tips for solving them? (Is the rider part of the motorcycle? Should I select a mostly-empty square containing a single handlebar?) All I've determined is that the system prefers contiguous sets of ~6 squares.
- CalRobert 3y agoNot sure but it drives me crazy when I have to knowingly miscategorize something because it thinks a motorcycle is a bicycle and vice versa.
