The controls within the system itself should be isolated (critical from non critical), the car itself could be networked if set up correctly. As for this idea right now that they are networked, they are but only for getting data back for testing purposes. The cars are designed to know nothing of their environment other than what it learns from it's sensors. The idea is the car must navigate a world of humans and so relying on things outside of that space it occupies would be a detriment to the vehicles success. You add in the fact many parts of the country don't have reliable enough satellite or cellular connections to trust it to control life safety equipment and you quickly understand why a lot of these concerns aren't really founded in reality.
In the future updates could be pushed to the system in ways I talked about in the post above, but even then it wouldn't require any special "network" to achieve only access to an update server that uses high end double blind encryption with the car itself (think VIN) holding a piece of the key no one could know otherwise without physically being there. If you wanted to take it a level further you could require all updates to require a physical action at the car, think pushing a physical button, to initiate an update which takes away the ability to remotely drive firmware changes.
