Every so often, usually after a firefox update, CF will get into a "I'm convinced your a bot" mode with me. I can get out of it by solving 20 CAPTCHAs.
I can't tell whether you're serious but in case you are, this theory immediately falls apart when you realize waymo operates at night but there aren't any night photos.
I'm certain the User-Agent is part of it. I know that for certain because a very reliable way I can trigger the CF stuff is this plugin with the wrong browser selected [1].
