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.
Mercedes got one good test from Edmunds that looks a little better in terms of km/kWh than a Model S (but not the Y or 3), and one duck from Nyland that showed them way behind. If you're trying to claim that car is clearly better then the only thing you can possibly be citing is... advertising materials. Practical realities say the production EQS fell way short of where it claimed it was going to be last spring.
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.
You claimed Tesla had superior aerodynamics to any other car on the market. That's factually not the case.
I always find it funny that people get so bought in to something as trivial as a car brand that they're unable to differentiate fact from fiction any more.
That's the power of advertising I suppose. They've advertised at you and it worked.
