Tesla adds Dog Mode, Sentry Mode

Tesla has added two new software features to the Model S, X and 3, thanks to one of its over-the-air updates. The first is Sentry Mode, designed to deter potential thieves. If someone leans on a car with Sentry activated, the car switches into an 'Alert' state and shows a message on the central touchscreen, warning the potential thief the car's cameras are turned on.
