FSD 14.3 rollout

Tesla has begun pushing Full Self-Driving 14.3, then followed with 14.3.2, a smaller update that early drivers said felt smoother in everyday use. (tesla.com; x.com) Full Self-Driving, or FSD, is Tesla’s driver-assistance system that can steer, change lanes, park and follow navigation routes, but Tesla says it still requires active driver supervision and does not make the car autonomous. (tesla.com; tesla.com) Tesla distributes FSD through over-the-air software updates, which download over Wi‑Fi and install from the car’s Software menu or the Tesla app. (tesla.com) In launch notes shared with owners, Tesla said FSD 14.3 cut inference latency by about 20%. In plain terms, that means the in-car computer is supposed to turn camera input into driving decisions faster. (x.com; tesla.com) Tesla describes its system as camera-based software running neural networks on an onboard computer, with the car building a model of the area around it before making steering and routing decisions. (tesla.com; tesla.com) That makes software revisions central to how Tesla markets FSD: the company says the feature set evolves through updates, and its current U.S. subscription price is $99 a month. (tesla.com; tesla.com) Tesla is also using the rollout to widen exposure. Its support page says owners in the U.S., Puerto Rico, Mexico and Canada with version 14.2 or later can receive a complimentary v14 trial on eligible Model S, Model 3, Model X, Model Y and Cybertruck vehicles. (tesla.com) The early reaction to 14.3.2 has centered less on new features than on driving feel, with social posts from owners and reviewers calling it the “smoothest” recent FSD build. That kind of feedback is subjective, but it tracks the company’s own emphasis on faster decision-making in 14.3. (x.com; x.com) The immediate test is whether more owners report the same thing as 14.3.2 reaches a wider fleet: fewer abrupt moves, quicker decisions and less need for driver correction.
