Will this work after the required migration to Facebook API v2+ that is coming on April 30? My understanding of one of the many changes this will drive is it will only be possible for apps to see your friends who also use the app. Apps won't be able to get full friends lists to do this kind of intersection any longer. Or is there a special relationship exemption for Lyft? Or maybe I misunderstand the FB changes.
