I've been reaching the conclusion that Tesla make Elon-mobiles.. i.e. the car is just there for what Elon wants and desires, and the rest of us just fund it by buying it. Model X debut timed with Elon's kids getting too big for the rear-facing seats, autopilot must be optimized for the 405, stability control can't be turned off because Elon totaled his F1, etc, etc.
This is how Ferrari used to/still does work. The car buyers fund the F1 team.
