Features like Storm Watch automatically prepare your system before severe weather.

Tesla is celebrating the Cybercab robotaxi launch with an exclusive, invite-only evening in Austin. Press reports and invitation emails fix the date as 3 September 2026. Tesla says it will livestream the event; everyday Robotaxi access after the night is still expected to start small, alongside the Model Y fleet already running in a handful of US cities.

    Employee Cybercab Rides Were the Reported Warm-Up for a Public Debut

    After 3 September, Cybercab Is Meant to Join Austin's Robotaxi App

    Electrek and other outlets say the launch is Cybercab joining the existing Austin Robotaxi service — the same geofence and FSD stack already used by driverless Model Ys — not a new city-wide network. How many cabs riders can actually hail remains unconfirmed.
