You don't get a NHTSA VSS of 0,38 by having a flimsy frame. Period. End of story.
You also don't get it from building a solid steel box.
You keep missing the point, so often that it's starting to seem deliberate now: there are no "unique loads of a hitch" that are more intense than the loads the frame will experience in a severe collision. On any axis. The forces exerted on a hitch are laughably small by comparison. On all axes.
And you keep missing my point. A hitch is a lever. If the cross beam was not built for that bending moment, it will deform.
What the bolts are attaching to" is a UHSS safety cell on a vehicle with by far the lowest combined probability of injury that the NHTSA has ever given out. They're the attachment of a critical crush structure to the safety cell.
That has no bearing on a torsional force.
The nothing, nothing, nothing and nothing - as extensively covered elsewhere. They literally could do nothing more than flag the vehicles as tow rated, buy Eco Hitches and converter-based wiring connectors, and use part of the funds from sales to pay for their installation at the destination (even from third party shops). They certainly can do more than that, but at a bare minimum, the only thing we need from Tesla is simply to give the vehicles a non-zero tow rating.
Only if it was built to have the vertical and torsion loads.
Yeah, the last thing we need right now is an American (aka, someone from a country where most people don't give a rat's arse about towing) lecturing Europeans about what they do and don't need.
No need to stereotype, I tow and haul. Thus waiting for the pickup... I get that you would like to haul, I hope Tesla made the 3 easily capable of such a thing, but I also understand why they would not have (time, money). The add one parts may need to be a subframe or backer plate for all we know.
Towing loads are...
Not. Remotely. Comparable.
... to crash forces. They're completely irrelevant to the structure they're bolted to. Your argument is akin to arguing that a person is going to make the wall of their house collapse because they hung a painting on it.
No they aren't, so why do you keep taking about crash/ impact instead of torque (my entire point)? Hanging a picture is an in plane load, exactly what walls are built to handle. Hanging a 3 foot deep plant hanger on a wall and then putting a large plant on it is not what a wall is built for. A wood framed wall will likely hold, but a light gauge metal stud wall may not...
Your link does not state what you claim. The problem people in the thread were encountering was the use of cabin 12V sources, which are on wires of limited gauge and virtual-fused. Model 3's DC/DC converter is 2,5kW. Even the 12V socket in the cabin can give 150W, well more than even the most powerful brake light / turn signal kit you could possibly put on a trailer.

I would expect Tesla to have a vehicle network controlled trailer lighting adapter as part of any future kit.
