According to Sawyer Merritt, Tesla has developed an AI-driven system that constructs real-time 3D drivable environments using footage from all eight cameras on its vehicles. This allows Tesla engineers to virtually 'drive' inside a highly realistic, fully simulated version of the real world, significantly enhancing the development and testing of Tesla's Full Self-Driving (FSD) capabilities. This innovation streamlines FSD training with real-world data, accelerates simulation-based safety validation, and creates new opportunities for scalable autonomous vehicle testing and AI-powered automotive innovation (source: Sawyer Merritt on X).
