I mean, everyone buys cars for different reasons, but in that range you're buying it for 3 reasons I can think of: to drive it fast, to look at it in your garage, or to boast about how much you paid. It's not ticking box 2 or 3. The non-flying model does seem to tick box 1, but the exclusive flying model seems to add nothing there (presuming it ever gets made how many billionaires are even going to survive using it?)
