FSD is incredibly reliable. Build quality of US built cars is middle of the pack, Europe/China built Teslas are top of the pack.
Oh c'mon now. Damn model 3 and model S I have driven were considerably lower quality interiors than an ass end Citroen or Fiat. The Model S, a 2023 model the doors didn't even fit properly. And that was all Europe.
As for FSD, nope. Unless you redefine the word reliable.
Edit: I owned a 2018 Model S as well. Literally the worst fucking car I have ever owned or driven.
Incredible shilling, bravo
