Cars are methods of transportation (and even though I'm a car enthusiast, who enjoys driving) they should be driver focused. The center screen in a Tesla is where _all_ the information is available for the driver. There are no secondary gauges or other driver-specific controls or displays. The car, presently, should be oriented for the driver to pay the most attention to the vehicle, the road, and their surroundings.
If there's a display behind the driver, or solely on the passenger side of the vehicle out of sight and reach of the driver, then it can be presumed to operate for the passengers of the vehicle.
