Two Tesla Cybercabs were observed operating together in downtown Austin, Texas, on December 28, 2025—following earlier sightings on December 18—continuing the vehicle's public road testing phase, as reported by Tesla enthusiast Sawyer Merritt on X.
Sawyer Merritt posted on X at 20:01 UTC on December 28: "Two Tesla Cybercabs spotted testing together again today in downtown Austin, Texas."
The post featured a video from a follower showing the pair in action. This builds on unconfirmed December 18 reports of single Cybercab tests on Austin public roads, after Elon Musk-confirmed driverless Model Y trials earlier that week.
Tesla's Cybercab, a fully autonomous robotaxi unveiled in 2025 without steering wheel or pedals, is advancing toward a ride-hailing network. Austin's role as a testing hub underscores progress amid regulatory and competitive challenges, though no official details on these specific activities were shared.
