Two things: One, this is maybe the one time in every hundred billion that YouTube popups are useful, and not the worst. And two, those popups actually do a halfway decent job of being the sort of HUD info-centric Terminator vision that we hope will happen someday for sports like horse racing, NASCAR, and hell, maybe football.
