I see what you mean, but I guess it depends on your definition of vapourware. I don’t think whether it’s publicly available is determinative. That fact that it’s called “full self-driving”, combined with the claims made about (let alone the money taken for it), and the length of time taken, render it vapourware for me. Duke Nukem Forever was the platonic vapourware, until it released as a complete product, at which point it ceased being vapourware. I don’t think anyone believes that FSD is the finished article, and those last few percent are critical where human lives are at risk. But I can see that reasonable minds may differ. It’s not a precise term.
