First purpose-built Cybercabs enter Texas DMV commercial fleet registrations, 3 days before the 3 Sep launch event
On 31 Aug Tesla registered 45 purpose-built Cybercabs with the Texas DMV in a single day, the first time they have appeared on the commercial operating fleet register. Until then, all 270 vehicles in the Texas fleet were Robotaxi-spec Model Ys.

The same day, the Robotaxi operating zone in Dallas grew by about 50%, to about 120 square kilometres, under FSD v15. On the supply side, the fleet has jumped from rebadged Model Ys to purpose-built Cybercabs with no steering wheel on the commercial register. Coming 3 days before the Cybercab launch event in Austin on 3 Sep, it is the hardest on-the-ground milestone ahead of the event.
Key evidence
- On 31 Aug alone, Tesla registered 45 purpose-built Cybercabs with the Texas DMV (confirmed by Not a Tesla App, Texas Autonomous Fleet Tracker and Tesla Oracle).
- This is the first time Cybercab has appeared on Tesla's commercial operating fleet register. Before this, all 270 vehicles in the Texas fleet were Robotaxi-spec Model Ys.
- The company has said explicitly that it is deliberately holding back from adding more Model Ys to the fleet and is moving straight to Cybercab.
- The same day, the Robotaxi operating zone in Dallas grew by about 50% on the FSD v15 build, to about 120 square kilometres.
- FSD v15 is running on 2 tracks: the Robotaxi fleet is on v15, while consumer cars will not get v15 until late 2026 to early 2027, according to the official timetable.
- This follows the 270 Model Ys of 29 Aug and the pace of Optimus production at Fremont reported on 28 Aug.
Catalysts to watch
- Cybercab launch event in Austin on 3 Sep: the test is the number of genuinely driverless commercial operations, not just registrations
- Whether later Texas DMV registration data show Cybercab numbers continuing to rise
- Further expansion of the Dallas FSD v15 operating zone, and ride order data
- Delivery on the timetable for v15 reaching consumers (late 2026 to early 2027)
Risks
- The 45 vehicles are registered (plated), which is not the same as genuinely driverless commercial operation on public roads. Third-party trackers saw the genuinely driverless fleet in Austin shrink at one point to about 17 vehicles.
- A 'registration push' and a 'real driverless ramp-up' are still 2 different things. Scale can only be checked after the launch event on 3 Sep.
- The plating was timed to a marketing milestone, and the motive includes an element of staging for the launch event, so it should be viewed separately from actual ride-taking operations.
- If the timetable for bringing FSD v15 to consumers slips, it would weaken the narrative that the Robotaxi stack will filter down to consumer cars.
