Doubts Remain Over Driverless Taxi Rollout in London

Autonomous vehicles are already being tested on London’s streets, effectively learning routes ahead of a potential commercial rollout of “robotaxi” services as early as September.

However, their future in the capital remains uncertain, as Transport for London (TfL) has yet to approve their operation.

Senior figures at City Hall have expressed reservations. Seb Dance, the Mayor’s Deputy for Transport, told the London Assembly that the overall benefits of autonomous vehicles (AVs) are still unclear. TfL Commissioner Andy Lord added that, under current rules, driverless vehicles would not meet existing private hire licensing requirements.

Major technology firms are pushing to bring AV services to London, including UK-based Wayve, supported by Microsoft and Uber, and US giant Waymo, part of Alphabet. These companies highlight safety advantages, such as adherence to speed limits and the absence of human error linked to fatigue or alcohol. However, officials argue more evidence is needed to determine whether these vehicles genuinely improve road safety.

Beyond safety, there are broader concerns. While AVs could reduce reliance on private car ownership, there are fears that large numbers of robotaxis could increase congestion and worsen air quality. TfL has already warned that the number of private hire vehicles—currently around 130,000—is approaching unsustainable levels, particularly with ongoing issues like cross-border licensing.

Accessibility, passenger safety, and the potential loss of jobs for existing drivers are also key issues. Liberal Democrat Assembly Member Hina Bokhari warned that the technology could pose a serious threat to current taxi and private hire drivers. In response, the Mayor’s office has confirmed that these impacts will be examined by a newly established AI taskforce. Support for London’s traditional black cab trade remains a priority, with officials emphasising its cultural and practical importance.

Industry voices are also raising concerns. Liam Griffin, CEO of Addison Lee, has warned that driver livelihoods could be at risk and has called for safeguards such as minimum pricing and limits on AV taxi permits to prevent unfair competition.

The legal framework is still evolving. While the Automated Vehicles Act 2024 sets out how AVs could operate nationally, it also allows for existing local licensing rules to be overridden. In practice, permits for driverless taxi services would be issued at a national level but would still require approval from local authorities such as TfL.

Exactly how this approval process will work remains unclear, and discussions between central government and London authorities are ongoing. TfL maintains that it has the authority to refuse licences if standards are not met, but there is concern that national powers could override local control.

Mayor Sadiq Khan has made it clear that any introduction of AV services must align with London’s wider transport goals, including reducing congestion and promoting walking, cycling, and public transport. Approval will depend on whether proposals support these objectives.

Experts have also urged a broader perspective. Professor Glenn Lyons from the University of the West of England cautioned that the debate should go beyond safety, focusing instead on whether autonomous vehicles deliver meaningful social benefits. He warned against shaping cities around the needs of robotaxis, rather than ensuring the technology serves the needs of the city.

With regulatory details still to be finalised, and key questions unresolved, the introduction of driverless taxis in London remains far from certain.
