A Tesla Cybercab prototype, equipped with temporary side mirrors and a human safety supervisor, was photographed navigating traffic in downtown Austin on December 21, 2025. This sighting marks an early phase of public road testing for the robotaxi vehicle ahead of its planned mass production in April 2026. The test vehicle features Texas manufacturer plates and the vehicle's signature matte-gold finish.
The Cybercab, unveiled at Tesla's We, Robot event in October 2024, was previously demonstrated driving autonomously on the Warner Bros. lot. However, this appearance on public roads in downtown Austin represents a significant step in real-world validation. Eyewitness photos captured the angular vehicle, distinct from the mirrorless production design, fitted with small triangular side mirrors to comply with Federal Motor Vehicle Safety Standards (FMVSS) for operator-controlled vehicles.
A human safety monitor occupied the front seat, likely to oversee operations and collect qualitative data on ride comfort and smoothness during stress-testing in urban traffic. Although the angle of the photos did not confirm the presence of a steering wheel, the setup suggests Tesla is conducting regulatory and safety evaluations. Temporary steering wheels have been observed on Cybercabs at Giga Texas in prior tests.
This engineering mule differs from Tesla's driverless Model Y robotaxis already operating on Austin streets, as current FMVSS rules mandate manual controls and mirrors for public road deployment. Tesla has advocated for federal regulations to exempt robotaxis from these requirements, but for now, such modifications are necessary. The testing phase is crucial with mass production slated to begin in April 2026, aiming to deploy the vehicle in Austin and the Bay Area to replace Model Y robotaxis.
In related developments, Tesla's broader robotaxi efforts include supervised operations in California, where the company has registered 1,655 vehicles and 798 drivers with the California Public Utilities Commission as of December 2025, up significantly from August's launch figures. However, these services require human oversight, highlighting ongoing regulatory hurdles for full autonomy.
