What if, instead of using both sides of the driver display (as seen in the concept MX) in order to display rear view video, the video was displayed on the pillars themselves. This would of course mean that the mirrors are in place on the current test vehicle as a back-up, to throw people off, or until this technology is approved. I think this is much more compelling than just "see-through" pillars
Possible. It could also explain removal of pillar covers, so that these screens are not seen in public.
Then again, I haven't been able to see any indication of mirror-camo over side cameras on the mirrors... I am mostly expecting the Model X to launch with regular mirror, as disappointing as that may be. Let's hope the pessimism isn't warranted.
Still, I think there is potential evidence of corner cameras: in the front fog light assembly and in the side of the rear lights, where there is a square cut-out in the camo. Those could be related to parking systems.
