At a Hollywood studio this October, Tesla unveiled its long-awaited robotaxi, though fans of the electric vehicle maker will have to wait until at least 2026 before it is available. CEO Elon Musk pulled up to a stage in one of the company's "Cybercabs," telling the crowd that the AI-powered vehicles don't have steering wheels or pedals. He also expressed confidence in the progress the company has made on autonomous driving technology that makes it possible for vehicles to drive without human intervention. Tesla began selling the software, which is called "Full Self-Driving," nine years ago. But there are doubts about its reliability. "We'll move from supervised Full Self-Driving to unsupervised Full Self-Driving, where you can fall asleep and wake up at your destination," he said. Tesla expects the Cybercabs to cost under $30,000, Musk said. He estimated that the vehicles would become available "before 2027." The company also expects to make the Full Self-Driving technology available on its popular Model 3 and Model Y vehicles in Texas and California next year. However, shares of Tesla Inc fell not long after the unveiling — investors don't see a clear timeline for the rollout of the Cybercabs, while other companies are already using similar technology. "Tesla yet again claimed it is a year or two away from actual automated driving — just as the company has been claiming for a decade," Bryant Walker Smith, a University of South Carolina law professor who studies automated vehicles, told The Associated Press. Tesla's announcement comes as US safety regulators are investigating Full Self-Driving and Autopilot based on evidence that it has a weak system for making sure human drivers pay attention. Last April near Seattle, a Tesla using Full Self-Driving hit and killed a motorcyclist, authorities said. The Tesla driver told authorities that he was using the system while looking at his phone when the car hit the motorcyclist from behind.
