I am the original owner and grateful driver of a 2017 Model S. My sister recently acquired a model Y, which she is also very happy with. However, a close friend of hers who is an ICE engineer/designer (hence, not a disinterested party) told her of a "Model Y design defect" such that in some turns, only 3 of 4 tires are in contact with the road. I've done a bit of searching on the web, as I would suspect that if this were true there would be substantial discussion of the issue -- and I find nothing. Does anyone have evidence-based comments to share relating to this issue? I'm guessing at the moment that it is going to turn out to be an unsubstantiated rumor and nothing more.
