Which reminds me, I am interested is seeing how they plan to incorporate the rear camera. My previous truck had a rear camera in the tailgate that, when the gate was open, gave a close-up view of the ball hitch. Since tesla needs to use the camera for other driving systems, I wonder if it will...
There is no flag required if there is no overhang. Flags are required with 4' or more overhang out the rear of the truck. Since most trucks are about 20 feet long, a 20 ft. board would have no overhang.
I've wanted to do this with my truck everytime I haul 16' & 20' boards but the movement of the rear axle always turned me off of the idea. The nice thing about the Cybertruck is that we will have a clear span with no moving parts to worry about.
Another thing to keep in mind, as I often see the argument that, "the switch to using castings means the exo is not strong enough" which is incorrect. From an engineering perspective, I can tell you that the casting was planned from day one.
The motors and suspension and all other vehicle...
It's unlikely that the midgate will fold. To be weight efficient, stress skin structure requires lateral structural bulkheads. The fwd. end of the box is the perfect location for this. I'm not saying it's impossible but it adds a lot more complexity than the average person would expect.
People who argue against the exoskeleton/stressed skin design must not be aware of an invention called the airplane.
It's the lightest and stiffest possible way to transfer loads through a structure. The reason you don't see exoskeletons on other trucks is not because cab-on-frame is "better"...
