As a speculative exercise, what do you think the global demand would be in the next couple years if current Model X was fully self driving? Based on the current business model for the auto industry of mostly selling to owner/drivers, there's a pretty limited demand for $80K + vehicles. Tesla planning on selling 100K or 150K of Model S and X combined is ambitious and threatens incumbents like Mercedes, BMW, Porsche. If the Model X was self driving however it could would make an excellent Uber Black/ Uber SUV style ride share app vehicle. Even at $80K it seems quite possible the global demand might be in the millions or even 10's of millions per year. As a self driving ride share vehicle every Model X would earn it's cost back pretty quickly and displace several, maybe half a dozen owned vehicles by being in constant use in a fleet. The market hence wouldn't be bound by the number of wealthy owner/drivers who could afford to have it sitting around parked someplace 95% of the time. This is just a thought experiment to highlight assumptions about the auto market, obviously M X won't be self driving for several years and if there was vastly larger demand Tesla couldn't begin to fill it anyway. Self driving though may be little more than a software update away for X. If everything else about the Model X including the price is held constant and there's a magical software update from the future to make it self driving, might the demand curve not shift dramatically?
