Tesla’s robo-taxi service can cover 25% to 50% of the U.S. population by the end of the year, pending regulatory approval, according to Musk. Tesla, however, does plan to launch a robo-taxi service in the first half of 2026 in seven new cities: Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas. The populations of those metro areas, plus Austin and San Francisco, where Tesla currently operates robo-taxis, total about 40 million, or about 11% of the U.S. population.
