I only have space here to address a few issues, so we'll start with the central seating position. I don't see how that helps a trucker. I already get "a commanding view of the road" in a traditional truck because I sit six feet above traffic. What I need is a commanding view of my own truck, which the central seating position compromises. The worst blind spot in a tractor is next to the doors; in the Tesla Semi, I can't lean over to see if there's a Toyota Corolla camped out beside me. The central seating position hampers my commanding view when I need that view most: when I back up. For any backing maneuver, I watch both sides of the trailer in my mirrors to make sure I don't clobber anything, or I lean out of the truck to watch the trailer as I back. Being able to physically watch the trailer not camera images on screens can be the difference between making a clean back-up or making an insurance claim.
Furthermore, I can't see around trucks in front of me without pulling halfway into another lane. When I need to exchange paperwork with the guard at a terminal, or the police, I can't lean out the window to do so. Speaking of which, I have to believe one of the windows on the Tesla Semi rolls down, but I can't figure out which one. If, as it appears from the renderings, the windows only vent, well... that's unacceptable.
That guy literally said he had only spent 9 months has a trucker. ---
