Tesla Robotaxi Roster Hits 420 Vehicles Ahead of Austin Cybercab Launch

Tesla Robotaxi, LLC now lists 420 vehicles on Texas’s official automated-vehicle registry, including 375 Model Y robotaxis and 45 purpose-built Cybercabs, according to a September 3 pull of the Texas Motor Carrier Credentialing System public lookup as the company hosts its Austin Cybercab launch event.

When Tesla North last checked the same TxMCCS file on August 31 for the Cybercab Texas roster story, Tesla had roughly 269 Model Ys plus the first Cybercab batch that climbed to 45 the same day. The Model Y side alone has added more than 100 authorized cars since then, lifting the total Texas robotaxi authorization from just over 300 to 420 while Cybercab VINs held at 45 under the 5YJA prefix.

A listing is still not a paid fare. Texas Senate Bill 2807 requires commercial Level 4 operators to keep an active vehicle list, insurance, and TxDMV authorization, and Tesla already used that path for Model Y Robotaxi service in Austin, Dallas, and Houston. Expanding the Model Y roster puts more cars into the same legal bucket that already covers the steering-wheel-free Cybercabs Texas registered ahead of today’s invite-only launch at Gigafactory Texas.

Tesla has not said how many of the newly listed Model Ys are already unsupervised on the road, or when Cybercabs enter the Robotaxi app for regular riders after the September 3 launch event. Crowd-sourced trackers and earlier company comments have pointed to a smaller active unsupervised fleet than the full authorization count, so the 420 figure is the regulatory ceiling Tesla filed in Texas, not a live dispatch total. The company also widened its Dallas service area late last week while paid rides still run mainly on the Model Y fleet.

Thursday’s Austin event remains the calendar date Tesla put on Cybercab’s public debut, and the state books now show a much larger Model Y base sitting beside those 45 Cybercabs as the livestream and invite-only rides get underway.
