Skipped to the last page so I might have missed the similar conversation. I really liked the D and autopilot features, and I will pay if Tesla offers retrofits to these features, once they become usable in Japan. After all lane markings, speed signs and other traffic rules are very different here so I guess it would take more time to adapt to international markets.
That said, I think Tesla could improve communication on this in Japan. They recently announced availability of Model S in September 2014, and just 37 signature owners received their cars (including mine) last month, after months (years) of waiting. In October Tesla announced the D, available in Japanese market in August 2015.
While nobody at Tesla Japan seem like to know the announcement in advance, many owners and reservationists here now feels that Tesla is not prioritizing Japanese customers. Elon seemed to say Japan is the third important market but nobody here believes that now.
It is always difficult to manage customer expectations but with this announcement Tesla lost a fair amount of trust from one of the most royal clients.
BTW I'm a very happy owner of P85. Sounds like sour grapes
but 21 inch doesn't fit in my parking, AWD not necessary In Tokyo, speed recognition won't work in Japan (in JP there're default limit values for highways and other roads, and if speed limit is not posted you have to follow the default), autopilot won't be enabled soon, etc.
