Tesla Full Self-Driving v14.3 Review: Major Improvements & Remaining Challenges (2026)

Tesla's recent resurgence in the European market is an intriguing development, but it's the advancements in their Full Self-Driving (FSD) technology that truly capture my attention. Personally, I think the improvements in FSD v14.3 are a step in the right direction, addressing some of the critical issues that plagued previous versions.

One of the most notable enhancements is the yellow light behavior. In the past, Tesla's FSD would often slam on the brakes at yellow lights, even when it was safer to proceed. This not only caused frustration for drivers but also posed potential safety risks. With v14.3, FSD demonstrates a more intelligent and cautious approach, making the correct decision to proceed through yellow lights without hesitation.

Another area of improvement is parking performance. FSD v14.3 seems to have mastered the art of efficient parking, a skill that was lacking in earlier versions. The system now navigates into parking spots with precision and speed, eliminating the need for manual intervention. This is a significant upgrade, especially for those who rely on their Teslas for daily commuting.

However, the navigation and routing system still presents a challenge. The confusion over routing directions and the car's tendency to ignore turns highlight the complexity of this aspect of autonomous driving. It's a critical issue that Tesla needs to address, as accurate navigation is fundamental to the success of FSD technology.

What makes this particularly fascinating is the human-like behavior exhibited by FSD v14.3. The system's decision to reduce speed and wait for an exit, rather than attempting risky passes, showcases an understanding of the situation and a willingness to adapt. It's almost as if the car is thinking ahead, considering the best course of action.

In my opinion, the larger visibility warnings are a welcome addition. By increasing the size of these alerts, Tesla is prioritizing driver awareness and safety. It's a simple yet effective way to ensure that drivers are informed about any potential limitations or challenges the system may face.

The stop sign behavior improvement is another significant milestone. In the past, FSD's erratic stops at stop signs disrupted traffic flow and caused confusion. With v14.3, the system demonstrates a more confident and logical approach, stopping only once at the appropriate point.

From my perspective, Tesla's continuous efforts to enhance FSD technology are commendable. While there's still work to be done, especially with navigation and routing, the progress made in v14.3 is a testament to their dedication to improving the driving experience.

As we look towards the future, I believe Tesla's focus on refining these autonomous features will be crucial. The potential for self-driving cars to revolutionize transportation is immense, and Tesla's advancements bring us one step closer to realizing that vision.
