Not really equivalent, as in a public space you have an expectation of being filmed (at least in the US.) Facebook isn't claiming anyone in those photos has agreed to anything, the law generally permits it unless the copyright ownership stands in the way. Your presence in any of those photos does not create an explicit grant to rights outside of the implicit grant created by the copyright holder that posts the photo.
To be clear, I’m not claiming it’s legal (or agreeing with the guy who says it’s no big deal). Just pointing out it is fairly equivalent. More than I expected before I started thinking about the comparison.
Would that make it the owner who is liable for any illegality, then, if they didn't inform their passenger(s) about the recording to which they, the owner, agreed?
