Tesla owners have been looking forward to OS 6.0, a software update for their vehicles, for a while now, but it’s finally rolling out to vehicle owners, reports Electrek. The system adds a bunch of new features for Model S vehicles, including a new Calendar app for in-car use, and big improvements to the Maps/Navigation software. What’s amazing (and surprising) for iPhone users is that they can now unlock and start their car from their devices if they forget their physical key fob at home. The update is yet another indication of Tesla’s commitment not only to future customers, but also to existing vehicle owners. Musk announced just last week that the Model S would get a warranty extension for its drive train of infinite miles for up to eight years.
