The introduction of fully autonomous vehicles in London faces potential delays amid regulatory uncertainties and unpublished guidance for operators. Several companies, including Waymo—backed by Google—the British start-up Wayve, which partners with Uber, and the Chinese firm Baidu, have expressed intentions to deploy driverless taxis on the capital’s streets. However, Transport for London (TfL) has yet to issue detailed instructions on how firms can obtain the necessary licenses to run fully autonomous passenger services.

Earlier this month, TfL granted Uber and Wayve licenses allowing autonomous taxis to transport passengers, but these services currently require safety drivers behind the wheel to take control if necessary. Despite government ambitions announced in May aiming for fully driverless cars on London roads by the end of 2026, the absence of clear regulatory guidelines has held back further progress. TfL’s director of strategy, Christina Calderato, informed the London Assembly transport committee last month that the authority is not yet ready to accept applications for fully autonomous services and indicated there is no rush to publish the required guidance, citing extensive ongoing work behind the scenes.

Prospective operators must secure an “automated passenger services” permit from TfL to run driverless taxis. The guidance for this application is pending, reportedly awaiting the outcome of a London Assembly investigation into robotaxi operations in the city. TfL also noted that no operator has completed the initial stage of the national approval process, which precedes final authorization by the local transport body.

Waymo aims to allow passengers to book driverless rides by the end of the year, subject to receiving the necessary regulatory approvals. Baidu commenced testing autonomous vehicles in London last month and plans to offer public rides in 2027. However, Wayve’s chief executive, Alex Kendall, clarified that a fully driverless launch within 2026 was never part of the company’s plans.

The Department for Transport emphasized safety as its foremost priority and stated that it is developing a "world-leading regulatory framework" to facilitate the safe introduction of self-driving vehicles starting in 2027.

While some see the cautious approach as necessary for safety and regulatory clarity, others express concern that the delay could hamper London’s competitiveness in autonomous mobility. Advocates highlight that cities in the United States, such as Los Angeles and Austin, already have fleets of fully autonomous cars operating. They argue that robotaxis have the potential to offer faster, cheaper, and more reliable transport options compared to traditional taxis, referencing data from Waymo indicating a significant reduction in serious crashes involving autonomous vehicles compared to human drivers.

Critics of the regulatory pace suggest that TfL’s hesitation reflects institutional resistance reminiscent of its initial approach to ride-hailing services like Uber. They contend that London risks falling behind other European cities, with Munich reportedly poised to become the continent’s first city to deploy full-scale autonomous cars. Meanwhile, TfL maintains it is committed to issuing guidance soon to support future applicants and ensure the safe integration of autonomous vehicles in the capital’s transport network.
