Should London Slam the Brakes on Autonomous Vehicles? Lessons from the New York Debate

A prominent US sustainable-transport blog has published an opinion piece arguing that the United States should scale autonomous vehicles (AVs) thoughtfully rather than hit the pause button. The article, on Streetsblog USA, directly challenges the site’s own editorial scepticism about AVs, offering a counterpoint built on safety data from Waymo and the Insurance Institute for Highway Safety (IIHS). While the piece is focused on New York, it raises questions that resonate strongly in London, where the Mayor’s Transport Strategy and TfL are already exploring AV pilots and where climate resilience targets demand a sharp reduction in car use.

The New York case: safety data and a pause

The opinion piece stems from New York City’s decision to allow Waymo’s testing permit to expire in March 2026, effectively putting the city’s AV programme on hold. The author argues that this pause is premature, given the safety record of Waymo’s autonomous vehicles. Quoting Waymo’s own data, the piece states that compared to a human driver over the same distance and environment, Waymo’s vehicles had 94 percent fewer serious injury crashes, 93 percent fewer pedestrian crashes with injuries, and 82 percent fewer injury-causing crashes. The IIHS, an independent research group, found that autonomous vehicles were 68 percent less likely to be involved in police-reported crashes, 85 percent fewer single-vehicle crashes, and 81 percent fewer injury crashes relative to human drivers.

The article also acknowledges a Hunter College analysis that raised doubts about AV safety, but notes that the lead author himself said the evidence was limited, comparing Waymo to “a rookie hitter who goes two for five in his first game and claims to be a .400 hitter.” The opinion piece urges New York to expand its pilot programmes, increase reporting, and create a statewide framework.

What this means for London’s AV pilots

London has been running its own cautious experiments with autonomous vehicles. The Smart Mobility Living Lab in Greenwich, a partnership between TfL, the Royal Borough of Greenwich, and several technology firms, has been trialling connected and autonomous vehicles (CAVs) on public roads since 2019. TfL also participated in the UK Autodrive project and the recent CAM (Connected and Automated Mobility) trials. However, the pace of deployment has been slow, and the technology remains largely confined to limited test routes with safety drivers.

The New York debate highlights a tension that London planners and policymakers must confront: the potential safety benefits of AVs versus the risk that they could increase car dependency and undermine climate resilience. The Streetsblog opinion piece argues that AVs can improve mobility for residents of transit deserts, seniors, people with disabilities, and overnight shift workers—groups that London’s transport strategy also aims to serve. But the same technology could also encourage more private car trips, adding to congestion and emissions if not paired with strong policies on shared ownership, electrification, and integration with public transport.

Climate resilience and the AV question

The category for this analysis is Climate and Resilience, and the AV debate is directly relevant to London’s climate goals. The Mayor’s Transport Strategy aims for 80 percent of all trips in London to be made by walking, cycling, or public transport by 2041. Reducing car dependency is central to meeting the city’s net-zero target and improving air quality, which is a climate resilience issue as well as a public health one. Autonomous vehicles, if they remain private cars that simply automate driving, could make driving more attractive and push back against that modal shift. Conversely, if AVs are deployed as shared, electric, on-demand fleets, they could reduce the number of vehicles on the road, lower emissions per mile, and free up space currently used for parking.

The Streetsblog piece does not directly address climate, but its claim that AVs can serve mobility-disadvantaged groups could be reconciled with London’s climate goals if the technology is part of a shared, low-emission system. TfL’s own research on AVs has emphasised the need to ensure that the technology does not worsen congestion or air quality.

Key facts

What London should watch next

The opinion piece recommends that New York expand its pilot programmes with more vehicles, a longer timeline, and public reporting to let the data speak. London’s current approach—small-scale trials with strict safety requirements—mirrors that cautious model. But the author argues that the evidence is already strong enough to move forward, not slam the brakes.

For London, the key question is whether the evidence from US trials is transferable to the capital’s dense, complex streets, where cyclists, pedestrians, buses, and taxis interact in ways that are less common in Phoenix or San Francisco, where Waymo has operated extensively. TfL has yet to publish its own comprehensive safety data from the Greenwich trials, and the public debate in London has been less polarised than in New York.

The next steps for London involve the government’s broader regulatory framework for AVs, which is currently being developed by the Department for Transport. The Automated Vehicles Act 2024 provides a legal basis for deployment, but local authorities like TfL will need to set conditions for how AVs operate in their areas. The London Assembly’s Transport Committee has previously called for a clear AV strategy that prioritises public transport and active travel.

The opinion piece also notes that AV deployment is creating manufacturing, maintenance, and fleet-operations jobs, most paying above the national median wage and requiring no college degree. London could benefit from similar economic opportunities, but only if the roll-out creates jobs that are accessible to Londoners and aligned with the city’s skills base.
