45 Cybercabs are registered to Tesla’s robotaxi fleet in Texas, and public rides in a limited area of Austin opened on September 4 through the company’s Robotaxi app. The launch event ran the previous evening, invite only, for existing robotaxi riders and sweepstakes winners aged 21 and over. The two-seat vehicle has no steering wheel, no pedals and no mirrors, and runs on Tesla’s AI4 computing stack.
NHTSA’s position is that it is in contact with Tesla and evaluating the situation. That sentence is doing a great deal of work. Federal motor vehicle safety standards are written on the assumption that a driver sits behind controls. The mechanism for operating a vehicle that lacks them is an exemption granted in advance, under Part 555 of the agency’s regulations. Tesla is operating first.
The Comparison Is Six Weeks Old
July 30 is when Zoox received the first commercial Part 555 exemption in NHTSA history, covering a purpose-built vehicle with no manual controls. Eight federal standards were waived explicitly, for up to 2,500 vehicles a year over two years, with conditions attached to how the vehicles may operate. The agency answered the question about manual controls before any paying passenger got in.
Tesla has inverted that order. The agency is now being asked to evaluate a configuration that is already carrying members of the public, which changes what a decision costs. Declining an application withholds a service that does not yet exist. Acting against a deployed fleet withdraws one that riders are using, in a state that has welcomed it. Those are not the same administrative decision, and the difference is the reason the sequencing is the story rather than the vehicle.
A proposal is not a rule, and this is where a good deal of the coverage has gone wrong. NHTSA floated dropping the steering-wheel requirement in a July proposal, and that proposal is being cited in Cybercab reporting as though the requirement were already gone. It is not. A notice of proposed rulemaking is a document seeking comment. Until a final rule is issued, the standards written around manual controls remain the standards in force.
What Scale Actually Looks Like
5,000 robotaxis is what Nevada has licensed Tesla to operate, against a first-year target the company’s own Cybercab chief engineer has put at roughly 2,500. Set either number beside the 45 vehicles registered in Texas and the gap between authorization and deployment is the honest measure of where this program sits. The launch is real. The fleet is a rounding error against the ambition, and both statements are true at once.
Roughly half of Uber’s fares is where Tesla has pitched Cybercab pricing, which is a claim about unit economics that only survives at volume. A two-seat purpose-built vehicle with no controls should eventually be cheaper to build and run than a Model Y with a safety driver. Forty-five of them in one metro do not test that proposition. Tesla’s US volumes give the company the manufacturing base to find out, which is the part of the strategy that is not in dispute.
The supervised Model Y robotaxi service Tesla already runs in Texas and Florida is unaffected, and it is worth keeping the two separate. GCBC covered the unsupervised Miami launch in July, when the company skipped the safety-monitor phase it had used in Austin. Those vehicles have steering wheels. The regulatory question opened this week attaches specifically to a vehicle that does not.
Watch what NHTSA says next rather than what it has said. The agency has a defined set of instruments available, from an information request through a defect investigation to enforcement, and choosing among them against a fleet already carrying passengers is a materially different exercise from ruling on an application. Whatever it does becomes the reference point for every operator that follows, which is why a 45-vehicle deployment in one city is worth more attention than its size suggests.
