Tesla added 150 Cybercabs to the Texas registry of automated vehicles on Thursday, its largest single addition so far, nearly doubling the number of its purpose-built robotaxis on the state’s list to 319, according to RobotaxiTracker.
The batch lifted Tesla’s total on the Texas Department of Motor Vehicles registry to 739 vehicles, up from 589, the first time it has passed 700.
The roster now holds 420 Model Ys and 319 Cybercabs, so the two-seat vehicle without a steering wheel or pedals accounts for 43% of Tesla’s registered Texas fleet.
When Tesla held the Cybercab’s launch event in Austin on September 3, 45 of its roughly 420 registered vehicles, or about 11%, were Cybercabs.
A registration does not show that a vehicle is carrying passengers.
It lists the vehicles Tesla is authorized to operate as automated vehicles under Texas law, not how many are in service on a given day.
Every Cybercab Addition
RobotaxiTracker polls the TxDMV registry hourly and records the first time each vehicle identification number appears.
Its data show seven rounds of Cybercab additions in under six weeks.
The first 45 appeared on August 31, three days before the launch event, in two batches of seven and 38 an hour apart.
Four more followed on September 8, taking the count to 49.
Nine were added on September 18 and nine more on September 21, alongside 19 Model Ys, bringing the Cybercab total to 67, with two more on September 22.
On September 25, Tesla added 57 Cybercabs in two batches of 19 and 38, lifting its Texas total past 500 vehicles for the first time.
Another 32 were added on October 1 and 11 on October 2, taking the Cybercab count to 169.
Thursday’s 150 came close to the 169 Cybercabs added in all six earlier rounds combined.
The Cybercab count has risen about sevenfold in the 38 days since the first batch appeared. All 319 are model-year 2026 vehicles, and their VINs carry the same Gigafactory Texas plant code.
No Model Ys After Sep. 23
The last Model Ys were added on September 22 and 23, one and 10 vehicles respectively.
Since then, all 250 vehicles Tesla has added to the Texas registry have been Cybercabs.
Before the Cybercab arrived, Model Ys made up every addition.
Tracking began on June 11 with 69 Model Ys already on the list, and Tesla added Model Ys in batches through the summer, including 57 on July 16, 79 on August 27 and 106 on September 2, the day before the Cybercab launch.
One Model Y has been removed from the registry since tracking began.
Tesla told JPMorgan in August that it was “intentionally holding back” on adding Model Ys to its robotaxi fleet while it prepared to scale the Cybercab, analyst Rajat Gupta wrote at the time.
The Texas Model Y count has not grown since September 23.
Registered Versus Spotted
RobotaxiTracker matches registered VINs against vehicles that community members have photographed or ridden in.
Of Tesla’s 739 registered vehicles, 325 have been matched to a sighting, 153 of them in the past 30 days, the dashboard shows.
Among the Cybercabs, 78 of the 319 have been matched by license plate, and none of Thursday’s 150 had been spotted by Friday morning.
The site’s Cybercab page lists 81 Cybercabs in its fleet directory that have carried community riders, with 39 riders logging 457 rides and about 2,624 miles.
McKanna said in September that Tesla had about 311 active vehicles across its markets in the previous 30 days, and cautioned against reading tracker totals as fleet size.
Tesla does not publish a robotaxi fleet figure. Its third-quarter production and deliveries report gives figures only for Model 3 and Model Y and for “Other Models,” without separating the Cybercab.
Tesla and Rivals on the Registry
Tesla received its Texas automated vehicle authorization on May 14, 2026, according to RobotaxiTracker, under a permitting framework created by Senate Bill 2807 and rules that took effect on February 27.
Those rules gave operators a 90-day grace period, which ended on May 28, after which commercial automated operation required authorization from the state.
Waymo has the largest registered fleet in Texas, with 1,185 vehicles, 197 of them added in the past 30 days, after passing 1,100 in late September.
Avride has 344 vehicles registered and Zoox has 17, the dashboard shows.
Tesla accounts for 32% of the 2,285 vehicles registered by those four operators, and has added 302 in the past 30 days, compared with Waymo’s 197.
Regulatory Backdrop
The registrations are growing while federal regulators examine how Tesla certified the Cybercab.
The National Highway Traffic Safety Administration gave Tesla until October 30 to provide sworn answers to a Special Order on the vehicle’s compliance with federal safety standards, granting 30 more days rather than the eight weeks Tesla had requested.
Tesla extended the hours of its Austin service to 11 p.m. last week, and Chief Executive Officer Elon Musk said avoiding pets at night was the main obstacle to running around the clock.
Tesla has listed Cybercab production capacity of more than 125,000 units a year.
