That's a different opinion than the one being expressed and therefore the I'm discussing. The argument I'm talking about is the one which claims, "There is no advantage to a two-speed transmission". You seem to be saying that the advantages of such a transmission are bad reasons to build it.

The post does not say those words.
The discussion of how Tesla can "already" achieve a fast 0-60 is a pretty clear acknowledgement that the number can be improved. But there's "no reason" because it's already so good, and there are important downsides.
That's all paraphrasing the post itself. It is not the blatantly false technical argument that you imagine.
And the post I made earlier was not a novel argument. It was taking "no [good] reason" and using that to classify a couple obvious "reasons" as not good. A very small logical step.
But those are different arguments.
