Tesla’s depreciation is almost identical to that of every other car model

Not at all. You might be okay with how fast yours depreciated, but that doesn't mean it's in line with other brands.

And BYD is a newcomer

They aren't- They've been making cars since before Tesla was incorporated. And they make more BEVs than Tesla, more battery cells than Tesla, and tesla uses BYD cells in some of their cars.

Just say that you don’t like Teslas

Okay. I liked my Performance Model 3 for the first 9 months, then it had serious problems. By the time I traded it, I hated it.

and/or Elon Musk

Great. Musk is a piece of shit. That's secondary, but still related to how abysmal Tesla's repair shops are, how few there are, and how long you need to wait for parts.

or that China is giving you money.

I wish. Yo, China. I'm willing to take money, and in exchange I'll promote BYD as an EV brand. If anybody in China with the authority to make this happen, DM me for wiring instructions. $500k USD a year, access to engineers internally so I can ask questions, and we've got a deal.
