The concern with BYD is they play the price undercutting game. They dont make as healthy profits as they should last I checked because they undercut everyone to spam markets with their cars. Companies who dont play the price game can build in healthy margins by not being seen as the "Cheap" car.
The leverage china has BYD aside is they make 70% of EV batteries. I know Elon has been looking to South America but still China's scale took decades to get to this point and nobody is seeing them production wise even when they try to move production off to others themselves.
Elon played his has too hard with the politics and shyt, and with Tesla = USA EV Industry because the other US manufactures are so incompetent we literally shot ourselves in the foot.
You would think US AutoMakers would be like Big Tech where they are too big to fail thus they are the forefront of global innovation for they field which keeps USA competitive.
Tesla does good in places where people have disposable income even though BYD is gaining steam but still they are seen as Spam in those markets, while in Latin America you see all types of BYDs since your Teslas and EVs from the other big dogs are not in those markets.
