ByD needs to be at least at 10% operating margins using Chinese workers, building in China, and selling to mostly the Chinese. If not then it's a DOA trying to compete in western markets. Once they set up shop paying westerner wages and putting up with their capex cost and red tape, BYD will go back to losing massive amounts of money.
Tesla is at least around 12% in Western countries 20+% in China for OM.
Since there is no public data on profitability market by market, how can you make these assertions. As for BYD are you assuming their business is only passenger cars?
As I have at least implied, if not said directly, I am not a great fan of BYD passenger cars. I am a fan of their busses, trucks and battery technology in some applications.
We should be promoting the Tesla mission here. That also means recognizing other companies that have similar goals.
FUD is undesirable, even when it relates to some company other than Tesla.
When the Nicola, Rivian etc have negative margins calling that out is not FUD.
Claiming BYD cannot succeed because their margins are more like legacy OEM’s than like Tesla’s is not factually likely, much less proven. Positive cash flow is a more relevant measure of their prospects, as it always is the best measure of survivability.
