My takeaway from all that you said is NOT (as you suggest?) to buy the fullest-optioned car Tesla offers - in order to best hedge my bets against their future arbitrary price and option "machinations".
My takeaway is: a ) ONLY buy a used Tesla, b) NEVER be an early adopter, c) ALWAYS ignore their incentives when they're trying to make quarterly numbers (and perhaps any time really).
Those Roadster 2020 folks who put $50K or $250K blind money down must be out of their FUSC'ing minds!
I guess Tesla's behavior, if it continues this way, should at least help buoy "pre-owned" prices.
PS: Anybody out there looking get in on a Model Y or Pickup? Beware! ( - any wise and thoughtful decisions you think you're making at the time will be "outsmarted" by Tesla) - BUY LATE or USED!
Is that the message Tesla is trying to send? It's working...
