> I wasn't saying that a Tesla and some economy car are identical,

You literally said:

> The only difference between a Tesla and an economy car from Stellantis is whether the software is well written or not.

You didn't say "one of many differences". You said "the only difference". Maybe you wanted to say something else, and you still can, but you can't claim it's my fault you said that.

> It should go without saying that software alone can't turn a Cherokee into a Model Y for the same reason that software alone can't turn a HomePod into an Apple Watch.

Which invalidates your statements that the cars "are software". They are more than software. They are a complex combinations of software and hardware, each of them having its part - and, obviously, if one of the parts is bad, it makes the car worse.
