One of the more interesting questions is, will the "base" Model S include auto-pilot (AP) hardware? My guess is yes. I just don't see Elon ever making a car that doesn't support AP. They are doing that now with the Model S. As the software improves there will be significant money on the table for Tesla, so for buyers who initially didn't pay to enable AP will likely pay extra to enable it. Also, the argument can also be made that the cars's added re-sale value will more then make up for the cost of the hardware. What do others think?
