This is getting very Gishy. I'll just repeat the original point upthread and depart: Teslas (and the model Y in particular) have poor rearward visibility because of a tapered afterbody, and this was done as a deliberate design decision (one of many) that makes them the most aerodynamic cars on the market. None of that has to do with towing or V2L.
Teslas are not the most aerodynamic cars on the market. The Mercedes EQS is. I think you're spending too much time with Tesla's advertising materials and not enough time with practical realities.
Again, the only car out there with a realistic claim (i.e. in independent testing) to be significantly better than a competing Tesla is the Lucid. And not by a lot, but it looks real.
