It's been pointed out how unfinished the design of dash must be because of the exclusion of vents, but as can be seen (heard) in this test drive demo, the dash has been designed to be "ventless," with some kind of invisible, single slot design instead. It's mentioned right at the beginning of the video. Not sure if this has been posted on before. A ventilation system that doesn't create drafts could be cool. Lack of adjustability not so much. And there's nothing to break up the flatness of it all.
