I bought my Tesla Model S about a month back and at that time, the map didn't recognize my home in a new subdivision. There were no street names (or even near by streets). Yesterday, the locality appeared with street names (even though the navigation from/to doesn't work). Does Tesla update navigation (and other computer controlled) features in a stealth mode? I know it keeps track of where I go! I would like to suggest that it uses face recognition to start the car. You can add drivers. It will prevent thieves as no thief would like to have his face photographed or recognized!
