If there is a cause for concern then there is a reason to do some research. Linking to a youtube video that has nothing to with these cars or BYD, and in fact talks about e-bikes doesn't qualify as research. If you asked Gemini "does BYD make exploding e-bikes?" it would have told you something like: "BYD does not manufacture e-bikes, nor is there any evidence linking them to "exploding" e-bike incidents. While the global e-bike market has seen a sharp rise in battery fires and thermal runaway incidents, these are primarily associated with unbranded aftermarket conversion kits and cheap, low-quality lithium-ion batteries rather than established automotive manufacturers." If you researched further you would find out why. BYD uses a completely different battery tech for instance. Again, you are basically saying "Because ... China" without offering any reason to come to the conclusion you have come to that "there is cause for concern."
