London Mayor Sadiq Khan has called for a limit on the number of robotaxis allowed on the capital's streets. In comments reported by the Guardian on 1 November 2026, he warned that a fast rollout could add to congestion and hit the livelihoods of black cab and private hire drivers. He said he did not want "a big bang without proper regulation in place", and that London's narrow roads make it very different from US cities where robotaxis already run. Under the current rules, Transport for London can only give or refuse consent for driverless services in the capital. It cannot license them or control how many there are, and Mr Khan says TfL is pressing the Government for more powers. Self-driving cars are already on London's roads in a limited way. Since 3 September, Uber and British company Wayve have offered rides in self-driving cars across London, with a TfL-licensed private hire driver on board to supervise every trip. In its results on 4 November, Uber said it expects about 700 fully driverless cars on its network by the end of 2026 and more than 2,000 in 2027. Freenow by Lyft hopes to launch fully driverless robotaxis in London as early as next year.
