It's definitely a work in process, but that's how beta prototypes are. The airbag unit isn't just a mock-up, it's missing, and there's some sort of electronics box on the floor. Probably the on-board computers or some test equipment before the finalized designs have been put onto fitted boards.
Looks like I got my wish! Dashboard drivers display behind the yoke!
Also those chunky pillars at the front that have smaller windows so you can see the road on front of the dashboard, as well as the chunky pillars where the chunky side view mirrors are... Trust me, that is some serious blind spots when turning especially in the city when pedestrians are crossing the street. You have to do some big leaning over to look around chunky pillars like that to make sure you see pedestrians and don't run them over. My Ridgeline has this problem with huge blind spots behind the pillars making it hard to see pedestrians.
The doors have speakers in them now. And it looks like a rough placement of either a tweeter or a passenger air bag in the pillar. It also looks like there is either embedded light up icons in the side view mirror, or some strange stickers applied to the bottom edge of the side view mirror. You can see they are further along in their design completion from the addition of drivers dash display and all these other smaller details.
