Thank you for posting these images. Our DS never touched on this oversized needle-like object lying loosely in the trunk.
Perhaps he thought we knew what it was and how we should secure it since he admitted we knew more about the features of the car than he did. I'm not gloating over our apparent knowledge of the vehicle at that time, however a number of Tesla associates at two different storefronts as well at their primary customer service mentioned the same as our DS, in that we knew more. Seemed odd to me. I mean, that's their job, to know their cars inside and out.
We took delivery forgetting about this loose chunk of metal on the main floor of the trunk (can see it through the window) until we arrived home. It has been sitting in our house ever since because I have not taken the time to research how to properly secure it in the car.
I opened the round Tesla cable bag this morning and thought, that elastic portion in the center of the rear-zippered area must be for the Tesla pen they gave me at delivery. Hmm. I must have overlooked this tow paragraph in the owner's manual.
Glad we have this forum to help with these things. Thank you everyone!
Still not sure where it is suppossed to attach in the event the vehicle needs to be towed.
