I think the main advantage that Tesla brings to this effort is the fact that they are creating everything in house. This means that they can concentrate on how the system works together as a whole and not have to fight about interfaces between disparate systems. Instead of having to learn how the entertainment center APIs work and writing code against that, they can just walk down the hall and talk to the people creating that code. I think that gives them a massive head start for this type of project. Plus, they have been writing automotive software for quite a while be well versed in it's peculiarities, not to mention the tooling they've likely created to help.
