It looks like there is some flexibility that lets everyone get their wish! The display is in a T-Slot that lets it be positioned anywhere along the dash, or hopefully even be slid right off passengers end and out the door. This is great for everyone: 1. Those who care about posture (& safety) and think head up is the way to go, can just buy no screen at all, or throw it in the attic as soon as they get home. 2. Those who demand silence from all other occupants can pretend to be polite by pushing a touch screen over to the passenger(s) while saying, "Here, look at this!" 3. Those in real estate who still want to guide their customers can use the head up for driver specific navigation and even scripting (think TelePrompter), while picking menu items off the left edge of the screen to control the narrative for the passenger. When some Tesla rep [Elon?] talked about Apple as a competitor, this is what they were thinking. (Maybe) Who will be the first to write a scripted [real estate] sales app for this combination? Here is a poll. Should you be able to ditch the screen completely?
