I have no doubt as to the ability of the motors to pull and stop a load. However, that is not my point. Old cars: overbuild steel with limited engine/ trans/ cooling.
You don't get a NHTSA VSS of 0,38 by having a flimsy frame. Period. End of story.
the unique loads of a hitch?
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.
I did not say anything about the bolt not taking the load, I am referring to what the bolts are attaching to
"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.
The rear structure of a car in a rear end collision is placed primarily into compression
Or shear. Depends entirely on the angle of impact. Even when perfectly aligned with the axis of the vehicle, initial force loads then tend to get translated into shear and torque on other elements (something stiffening elements try to resist). Think of crushing an alumium can - what's initially purely compressive force then gets translated into bending and twisting.
A 1850kg Model 3 in an accident decelerating from 30 m/s to 0m/s in 1/4 second is experiencing an average of 4,2MN force. A 250kg trailer undergoing 1G acceleration or braking is experiencing
1/2000th that force. There's more than three orders of magnitude difference between the two. If we were to analogize the force of a Model 3 in an impact to the weight of a 70kg human standing on the floor, the force of a trailer accelerating or decelerating
at 1g would be analogous to the person holding 8 Hershey's Kisses in their hand.
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.
Then they should get a car that fits their needs
Why, great idea! By all means, please point us to the low-cost highly-efficient dual-motor supercharging good-performing AP-capable OTA-updated out-now vehicle that you're picturing as an alternative.
or deal with the compromise
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.
Or complain that Tesla should have taken the extra time, effort, money, and trade offs
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.
I did not say the battery cannot drive the lights. The 3 monitors the 12V battery, the 3 charges the battery from the HV pack, the 3 knows how much charge it put in the battery, the 3 throws a fault if the 12V battery drains too quickly ... See:

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 realistically put on a trailer. You think the car is going to cut out if you plug something into the 12V socket?
ED: Just saw the mod note. Do we have a thread somewhere?
