Update, August 18, 2026: Tesla kept shipping the v14 line after this Christmas-week point release. A later Tesery note covers FSD v14.2.2.5, then the v14.3.3 and v14.3.4 builds. Consumer FSD is still labeled Supervised. A holiday point release is not unsupervised Robotaxi.

Tesla pushed Full Self-Driving (Supervised) v14.2.2.1 to some cars on December 23, 2025, as vehicle software 2025.45.6. Tracker Ming (@tslaming) logged that build one calendar day after v14.2.2 (2025.45.5, December 22). The original Tesery headline called it a Christmas gift. The software date is December 23 — Christmas week, not December 25.

That is a fast point release. It is not proof that Tesla “solved autonomy” over the holiday, and it is not a public-road Robotaxi license. Testers described polish on rain, parking, and steering feel. Tesla’s own product name still says the driver stays responsible. See Tesla’s Autopilot / FSD support pages for the current legal wording.

GOOD NEWS $TSLA FSD V14.2.2.1 ROLLING OUT NOW. This maintenance release is to polish what have been available in 14.2.2. V14.2.2 (2025.45.5) — Dec.22, 2025. V14.2.2.1 (2025.45.6) — Dec.23, 2025.

What testers said about rain and parking

Zack posted a long first-drive note on December 24 after several night runs in rain. He reported no steering hesitation or stutter, confident lane changes on wet pavement, and parking that usually finished in one take — including a tight spot that needed a sharp turn. He also said FSD still “saw” faded L.A. lane lines when standing water hid them from a human eye. That is one tester’s night, not a Tesla safety study.

5 drives in with FSD v14.2.2.1: zero steering hesitation or stutter, confident lane changes. All my drives tonight have been in the rain. Parking was very good, even with obscured parking lines. Took it up a dark, wet, twisty canyon road and it stayed centered.

Zack also logged limits. One park left extra room because a neighbor sat on the line. He saw one slow creep on a dark, wet unprotected left. He could not fairly compare rain-night v14.2.2.1 with the prior day’s clear-weather v14.2.2. Those caveats belong next to the praise. “Confidence inspiring” is a feeling, not a crash-rate delta.

What v14.2.2 already added

Ming and other owners treated v14.2.2.1 as a polish pass on v14.2.2, not a new feature dump. The v14.2 cycle is where Tesla added owner-facing Arrival Options — parking lot, street, driveway, parking garage, or curbside — and started moving the navigation pin to match the chosen drop-off. That is useful for a future ride-hail product. It is still a supervised feature on a car with a driver in the seat.

The same v14 series later grew Summon, nag changes, and a passenger-facing UI. Tesery’s later v14.3.4 note is the place for that stack. Do not read a December 2025 point release as if those later builds already existed.

Supervised FSD is not a Robotaxi license

Zack compared the steering feel to Tesla’s Austin Robotaxi rides. That is an analogy from someone who has sat in both. It does not mean consumer v14.2.2.1 is the driverless stack, and it does not change the law. Tesla still markets FSD as Supervised. Public-road approval is country-by-country. Tesery’s Giga Berlin factory-mile story is the reminder: miles on private plant roads are not German public-road FSD.

For owners, the practical takeaway is narrower. A holiday point release can land in the car overnight. You still have to watch the road. If you gift or subscribe to FSD, you are buying supervised time, not a robotaxi token. Check the car’s software screen for the exact build before repeating version numbers from social posts.

FAQ

Did Tesla release FSD on Christmas Day 2025?

No. The v14.2.2.1 / 2025.45.6 build was logged on December 23, 2025 — Christmas week. Christmas Day was December 25.

Is v14.2.2.1 unsupervised?

No. Tesla labeled it Full Self-Driving (Supervised). The driver remains responsible.

Did Tesla publish official release notes that day?

Tesla’s in-car notes for the v14.2 cycle listed Arrival Options and related parking/drop-off behavior. The rain and canyon-road claims in this story come from owner posts, not a Tesla safety paper.
