Which serial numbers? I see no evidence of any customer shipments with this capability. Happy to be corrected with factual evidence, though.

> I said Tesla product, namely something that is sold to customers as is.

That’s not what the word “product” means. It’s not limited to products shipped to end users. Components used only in service stations, dealers, or for their own internal use that are produced by them are also products. Quite literally anything that comes out the output side of a production process is a product.
