Tesla’s active robotaxi fleet in Austin crashes back to 8 vehicles after Cybercab pump

This is Tesla news, not a home energy story, but here's what happened: Tesla's robotaxi service in Austin briefly spiked to more than 100 active vehicles in early September, right after a launch event for the Cybercab (Tesla's driverless robotaxi model) drew a wave of influencers and first-ride videos. Within weeks, that number collapsed back to just 8 vehicles actually carrying passengers in a given week — roughly the same as when the service launched in June 2025.

Tesla has registered 476 vehicles for autonomous driving in Texas, including 67 Cybercabs, and that registered count keeps growing. But registering a vehicle with the state isn't the same as putting it on the road. Trackers could only match 265 of those registered vehicles to license plates seen in service, and just 179 were spotted at all in the past month. The gap suggests Tesla is limiting how many robotaxis operate at once, likely due to ongoing safety concerns about running the system at larger scale.

None of this affects home energy programs or rebates. It's a look at how a highly publicized product launch produced a short burst of activity that didn't translate into lasting growth for the service.
