Tesla FSD 14.3.10 feels like a noticeably more refined update. In this video, I put the latest version to the test and see how it handles real-world driving, from smoother decision-making and better lane behavior to overall confidence behind the wheel. Rather than introducing one flashy feature, 14.3.10 seems focused on polishing the FSD experience and making it feel more natural, predictable, and complete.

Is this the most refined version of FSD 14 yet? Let’s test it and find out.
