The clearly about towing thread, per the title, gotcha. Being the OP of a thread has nothing to do with wandering topic. If you wanted someone to find your general feature discussion (seems the whole point of a discussion), then a so-titled thread is clearly best. Nice 'n easy.
I see no reference to towing in the Model Y manual, which doesn't mean yes or no. (did I miss a reference in the manual? Page#?) The Y clearly has a place on the back to facilitate a towing jack so I think it's very presumptuous to immediately assume that Y won't have towing.
To worry about...
