Tesla registered 45 Cybercabs with the Texas Department of Motor Vehicles and staged public demonstrations in Austin on September 3–4, 2026, at the Gigafactory Texas and ACL Live, as the company advanced its Robotaxi testing program in the city.
The move matters because the registrations and public appearances mark a significant step in Tesla’s plan to scale a driverless fleet under the state’s new regulatory framework, and because the program is unfolding alongside active safety reviews and a local investigation after a collision near Zilker Park. Latest update: September 4, 2026.
Registration and fleet numbers
Tesla’s filing added 45 purpose-built two-seater Cybercabs to the roster of autonomous vehicles registered in Texas, bringing the company’s statewide total to 314 robotaxis. The vehicles were registered with the Texas Department of Motor Vehicles and are described as lacking traditional controls such as steering wheels and pedals. The Cybercab was first unveiled on October 10, 2024, and Tesla’s broader Robotaxi service began operating in Austin on June 22, 2025, initially covering approximately 18-20 square miles with safety monitors on board. The legislative context for this expansion is Senate Bill 2807 passed during the 89 th Legislative Session which created the Automated Vehicle Authorization and Enforcement Program that sets parameters for Level 4 autonomous operations and aims for full implementation by 2027.
Public events, features and regulatory evaluation
Tesla organized an invite-only launch at Gigafactory Texas in Austin on September 3, 2026, followed by a public debut at ACL Live in downtown Austin on September 4, 2026, where the Cybercab appeared to audiences at 4:45 p.m. The Cybercab’s design includes gull-wing doors, a golden body, injection-molded recycled panels, a brake-by-wire system and a dry cathode battery pack; Tesla described the vehicle as engineered for longevity and extreme efficiency. The National Highway Traffic Safety Administration has active evaluations focused on Tesla’s camera-only sensor approach and has documented at least nine crashes in related probes; the agency is scrutinizing how the system performs in reduced-visibility conditions such as fog and sun glare. Tesla confirmed the Cybercab demonstrations were tests and not a fully commercial service open to the general public, while representatives described the registrations as a substantial step toward scaling the Robotaxi program.
Collision near Zilker Park and local investigation
The rollout has encountered a serious incident: on September 1, 2026, a Cybercab struck and killed a 4-year-old golden retriever near Zilker Park in Austin. The vehicle was operating without a human occupant and did not stop after the collision, according to witness accounts. The matter is under investigation by the Austin Police Department. The dog’s owner, Elena Vasquez, said, ” He was just being a dog. I want answers about why that car didn’t stop.” The incident intensified local scrutiny of the Robotaxi service and prompted renewed attention to operational safeguards and reporting requirements under the state program.
Tesla’s fleet in Austin and its broader plans remain in active development as the company balances public demonstrations, regulatory evaluation by NHTSA, and local law enforcement inquiries. The company faces competition from established autonomous operators such as Waymo which currently operates larger fleets in other regions, and observers note the Cybercab is a direct product-level response to that competition as Tesla seeks to broaden its service area beyond Austin to other Texas cities including Dallas.
