description: "$Tesla(TSLA.US)Tesla launched a **30-day free trial** (actually about 40 days, covering the Christmas and New Year holidays) of FSD (Supervised) v14.2 for approximately 1.5 million HW4 (Hardware 4) vehicles in North America (the U.S., Canada, Mexico, and Puerto Rico) around the end of November 2025 (approximately November 28). This is the largest FSD free trial promotion in recent years, available only to owners who have not purchased FSD (those who have purchased or subscribed are unaffected, and subscribers may receive an additional month). This move demonstrates Tesla's high confidence in the maturity of the v14 version. Below are the positive developments and key data observed so far (as of December 1, 2025):### Significant Performance Improvements in FSD v14- Community tracking data (e.g., TeslaFSDtracker) and user reports show that v14 has made significant progress in "miles between critical interventions":  - Overall, approximately 732–1,677 miles per intervention (some analysts claim it's an order of magnitude better than v13).  - In urban driving scenarios, it can achieve up to 834 miles without critical intervention.  - Many users report it "drives like a confident human," "changes lanes more precisely than humans," and "makes them consider buying FSD for the first time."- Initial user feedback is overwhelmingly positive (just 2–3 days into the trial, with many reports on X/Twitter):  - Several owners described it as "mind-blowing," "completely changed my perspective," and "the garage auto-parking is stunning."  - Some completed their entire commute without any intervention, while others called v14 "a true game-changer."- Even owners who previously gave up on FSD have resubscribed or are considering a one-time purchase."
