Tesla's Full Self-Driving (FSD) system has undergone a dramatic transformation over the past six years. What started as a $6,000 gamble for Tesla owners has now evolved into a sophisticated autonomous driving technology that can navigate highways, city streets, and even handle complex maneuvers like parking. The article explores the early days of FSD, Tesla's data-driven approach to improving the AI, the advancements brought by Hardware 4, and the remaining challenges in achieving true Level 5 autonomy.

Why it matters

The evolution of Tesla's FSD represents a significant milestone in the development of autonomous driving technology. As the system continues to improve, it could pave the way for a future where self-driving cars become a reality, potentially transforming transportation and reducing the burden of driving for many people. However, the journey is not without its challenges, as the system still requires active driver supervision and needs to achieve a level of perfection exceeding human capabilities.

The details

In the early days of FSD, the system offered automatic navigation on interstate highways, smart cruise control, and lane steering on roads with clear markings. However, it struggled with more complex scenarios like rotaries and city street navigation. Tesla's unique approach to improving FSD involves leveraging the collective data from its vast fleet of vehicles, creating a continuous learning loop that refines the AI. The introduction of Hardware 4 in 2024 unlocked significant improvements, with FSD Supervised v14 receiving rave reviews for its enhanced performance and reduced need for driver intervention. Recent test drives of FSD v14.2 have demonstrated the system's ability to navigate complex intersections, handle lane changes in heavy traffic, and even execute autonomous parking maneuvers. However, the system still exhibits occasional inconsistencies and requires intervention in certain situations.

  • In 2019, the initial version of FSD was released, offering a glimpse of what was to come.
  • In mid-2024, Tesla began installing Hardware 4 in new vehicles, unlocking significant improvements in FSD capabilities.
  • Tesla is currently testing its Robotaxi program in Austin, Texas, where vehicles operate without a driver at the steering wheel, relying solely on FSD v14 and a supervisor with a kill switch.
