New-and-improved versions of the Tesla Model S and X could be right around the corner. Tesla's original family passenger vehicle, the Tesla Model S, hasn't had a serious overhaul since the 2016 model year. That's when it received a restyled front fascia without the black faux-grille panel and began picking up new features like Autopilot 2.0 with Enhanced Summon, and later, Sentry Mode. But recently, a number of observers have picked up on indications that a new overhaul could be coming to Tesla's flagship Model S sedan and Model X crossover soon. Now, we can add one more item to the evidence list: some lines of code within Tesla's latest software update pertaining to a cabin-facing "selfie" camera in the interior.
