...for a design about absolute efficiency there are some odd legacy auto carryovers that are no longer needed.
Simpler manufacturing due to centralized location. (Lowers unit cost)
Using a single large screen instead of 3 lowers component cost. (Lowers unit cost)
Aesthetically differs from legacy auto, "futuristic". (Increase target market appeal)
>Massive reduction in driver head movements. (Decrease driver fatigue)<
When using cameras and not physical mirrors with physical limitations, you no longer need to conform to the placement that was dictated by the physical limitations and can optimize for driver experience.
