As usual whenever Elon is involved people turn of their brains just so they can not admit that Elon or his companies did something well.
Nobody says this is the first time V48 has ever been used for anything. That literally just missing the point.

And if you go and take apart these Mercedes cars you will see that the waste majority of all of the devices and the wiring use the exact same 12v architecture that all the ICE cars also use.
