For some reason I can't highlight the text to copy and paste, but in the features section the key is mentioned:
"Programmable for individual drivers, the Tesla key loads preferred setting (seat, mirror, steering wheel positions) and commands the door handles to slide out as you approach. Model S turns on as you buckle up."
Now that buckling up thing is very cool.
Boot space with seats folded is 1838l, almost as much as the cargo-mighty Merc E-class, and way more than 5 series estate, Volvo or Audi. Without folded, it's still 1000 or so litres, which is absolutely incredible.
EDIT: Looking through more of the Model S section, I've come to the conclusion that this is the most beautiful, functional and desirable car I have ever seen or heard of. The interior blows me away, as does everything else! As far as I'm concerned Tesla's goal of electrification of transport is as good as accomplished, I'm sure they'll follow this with an equally as desirable bluestar (eventually).
