Tesla has launched its long-awaited Robotaxi service in South Austin, featuring driverless rides in the 2025 Model Y SUVs. CEO Elon Musk praised the AI software and chip teams for their decade-long efforts, tweeting, "Both the AI chip and software teams were built from scratch." The service, currently invitation-only, offers rides for $4.20 each, emphasizing Musk's belief in vision-only autonomy. This milestone could redefine urban transportation, challenging competitors relying on lidar and mapping technology.
