I may be tired from too much assembly language today, but... isn't the article saying that the Shanghai-made Teslas did best in a comparison with other cars sold in China, while the Fremont-made Teslas did worst in a comparison with other cars sold in the US?
If the two Teslas are equal in quality, or the Shanghai-made ones would score worse than the Fremont-made cars if rated by US buyers, then the implication is that ~all cars sold in China are qualitatively worse than the worst sold in the US. Which sounds implausible too me, perhaps even a case of RAA.
