Johan,
You have to keep in mind this is Tesla Model S version 1.0 or whatever you want to call it, the Apple iPhone equivalent of the original iPhone. Sometimes in order to make things better, they have to temporarily take away features, to enhance them. Especially in the case of Tesla there are many regulatory bodies in place to protect the human lives that are in Tesla's (capable) hands. This car is pretty close to perfection already IMO, but there will definitely be some small bumps in the road to such a radical change of automobile. Even the manufacturers that have been at it for over a century make more mistakes than Tesla has yet, and they aren't nearly as innovative. IMO just my 2 cents.
Exactly. Also, it took Apple with its army of programmers about 3 years to get iOS to where it was decent and 5 years I think to include basic things like 'mark all read' on email. Tesla certainly has a lot of work to do on things like the Nav to bring it up to feature parity with even a $200 GPS unit but 6.0 sounds like it is a big step in that direction.
