Update, August 18, 2026: The “about three weeks” clock from December 9, 2025 did not land at year-end. On January 22, 2026 Musk posted that Tesla had just started Austin Robotaxi rides with no safety monitor in the car. CNBC said that applied to some Austin cars, not the entire fleet. Tesery’s later count is the scale check: a citywide Austin map with about 20 Robotaxis running. Removing the passenger-seat monitor is not the same as a large unsupervised fleet, and it is not Cybercab volume production.
On December 9, 2025, at an xAI hackathon, Elon Musk said unsupervised driving was “pretty much solved” and that Tesla Robotaxis would operate in Austin with no one in the car — not even in the passenger seat — in about three weeks. Electrek reported the remarks the same day. Sawyer Merritt posted video of the line. Three weeks from December 9 is roughly December 30, 2025 — the end-of-year date Musk had already used in September, on the October Q3 call, and at the November shareholder meeting.
That was a schedule, plus a claim that validation was the remaining work. It did not, on December 9, put an empty Tesla on South Congress. The original Tesery headline said he “confirmed” removal. He restated a deadline he had already missed or slid several times. The original draft also opened a section with “Houston.” The city in the quote is Austin.
Key facts
- When he said it: December 9, 2025, xAI hackathon.
- What he said: Austin Robotaxis with nobody aboard in about three weeks; unsupervised is “pretty much solved”; Tesla is “just going through validation.”
- What Austin looked like that week: Paid Robotaxi rides still used a Tesla employee as a safety monitor — typically in the front passenger seat in town, and in the driver’s seat on the highway. Bay Area rides still required a monitor in the driver’s seat.
- What happened next: Public unsupervised Austin rides were announced January 22, 2026 — about three weeks after the year-end date, not three weeks after the hackathon.
- What it is not: Proof unsupervised FSD is “solved,” a Cybercab you can hail, or a nationwide robotaxi network.
NEWS: Elon Musk says FSD Unsupervised is “pretty much solved at this point” and that Tesla will be launching Robotaxis with no safety monitors in about 3 weeks in Austin, Texas.

What “safety monitor” meant in Austin in December 2025
Tesla’s Austin Robotaxi was not a steering-wheel-free Cybercab. It was a Model Y (or similar owner-style Tesla) in a geofenced service, booked in the Tesla app, with a company employee on board. In town the employee often sat in the passenger seat so the car looked closer to unsupervised. On highways the same person moved to the driver’s seat. That is a human fallback with a belt, not a remote-only robotaxi and not Waymo’s empty Jaguar.
Taking that person out is a real operational change. The car then has no one who can grab the wheel. Tesla can still use teleoperation or pull the car out of service. Later Tesery coverage of two teleoperator-controlled Robotaxi crashes Tesla disclosed to NHTSA is the reminder that “no one in the car” does not mean “no human in the loop.”
How many times Musk had already said “end of year”
September 2025: “Should be no safety driver by end of year.” October Q3 2025 earnings: Tesla expected no safety drivers in at least large parts of Austin by year-end. November shareholder meeting: same end-of-2025 line. December 9: “about three weeks,” which is just a more precise wrapping of the same year-end promise.
Repeating a date is not the same as meeting it. The useful test is whether empty cars actually took paid riders, in how many vehicles, in how much of Austin, and whether highway vs city rules changed. Tesla did not publish a fleet count at the hackathon. Later Tesery reporting put the running Austin fleet on the order of 20 cars even after the map looked citywide. That is the denominator the December quote left out.
What Musk also said that night (and what to park)
In the same remarks he said the no-monitor step would be done with a “quite small” model; a roughly 10× larger model would come in January or February 2026, with more reasoning and reinforcement learning; AI5 was still a design-stage chip with volume later in the decade; Tesla might need its own giant chip fab. Those are separate claims. None of them is evidence that the three-week Austin monitor removal happened on time. Do not fold chip-fab talk into a Robotaxi operations lede.
Did “unsupervised” arrive on December 30?
No public Tesla or city record shows Austin dropping all Robotaxi monitors on December 30, 2025. The first widely reported paid-looking rides with an empty front row were mid-to-late January 2026. Musk’s January 22 post is the company-side marker. CNBC’s wording matters: some vehicles, not every Austin Robotaxi. Texas later wrote more explicit rules for commercial driverless operation; Tesery’s Texas driverless-law note is that legal track. Dallas/Houston unsupervised expansion is a later story: Tesery’s Dallas and Houston piece.
Consumer FSD (Supervised) on an owner’s car is a different product. A holiday FSD point release does not remove the Austin monitor. See Tesery’s v14.2.2.1 note for the software cadence; do not treat that as Robotaxi unsupervised.
FAQ
Did Tesla remove Austin safety monitors in December 2025?
Musk said it would happen in about three weeks from December 9. Public unsupervised rides were announced January 22, 2026, and only on some cars.
Is that the same as Level 4 or “FSD Unsupervised” for owners?
No. Robotaxi in a geofence with Tesla’s own cars is not an over-the-air unsupervised mode for every HW4 Model Y. Tesla still sold consumer FSD as Supervised.
How many unsupervised Robotaxis did Austin have?
Tesla did not give a number on December 9. Later Tesery reporting put the running fleet around 20 even when the service area looked citywide. Always ask for the count, not just the map.
Does “no one in the car” mean no remote operator?
No. Tesla later told NHTSA about low-speed Robotaxi events under teleoperator control. Empty seats and empty control rooms are different things.
For owners: an Austin Robotaxi without a monitor does not change your car’s legal duty. You are still the driver on FSD (Supervised). If you ride Robotaxi, check whether a Tesla employee is in the front row before you treat the trip as driverless.
