Distinguishing “demo” from “marketing stunt” here feels like a distinction without a difference and smells like motivated reasoning.
replyI'd take "demo" to mean "product demo", and there is not going to be any product that drives vertically or upside down, nor does aerial flips - i.e. any of the stuff that was "demonstrated".
replyYou seem triggered by the choice of wording. Do you think the upside down rocket car doing aerial flips deserves a more product-ish name like "concept car"? I don't.
> wonder what the point of this was?
replyCar manufacturers have been doing pointless things for over a century [1], with no plan to even try to make them available to the public. Why is this getting so much heat?
