DJI is bad example as they are pretty much only consumer drone you'd ever wanna buy. It absolutely decimates competition. It's more like Tesla.

Not sure what you trying to say about BYD. I don't like them as cars, my friends do indeed have reliability issues and early ones are super uncomfortable. Latest ones are tacky with crappy software. IMO there's a lot of hype about them for some unknown reason. You can get vastly better deals over here.
