Tesla has recently made a significant step in the realm of autonomous driving technology with the release of Full Self-Driving (FSD) Beta version 12.1.2. This update, which is now available to a group of non-employee Tesla owners, represents a crucial milestone in the evolution of Tesla's advanced driver-assist system (ADAS). The update is particularly notable for integrating an end-to-end neural network, a shift from the previous reliance on explicit C++ coding. This neural network, trained on a vast collection of video clips, is expected to enhance the system's ability to navigate complex driving scenarios.
