It does look neat, but the driver's seat in middle would be annoying for the driver. Unless Telsa is putting cameras on the trailer, most drivers like being able to look out the window to perform backing maneuvers. Also, I wonder if Tesla is working on solid state batteries. If they can manufacture a ssb, that would be game changing. Supposedly, a ssb is about 10% more energy dense than liPo and can fully charge in 10 to 15 minutes.
