The arrival of fully autonomous vehicles on UK roads has been pushed back by another year, with the Department for Transport (DfT) now targeting the “second half of 2027” for legal approval of driverless technology.

There was an original goal of 2026 set out in last year’s Automated Vehicles (AV) Act.

It envisaged self‑driving cars operating without a human in the driver’s seat by late 2026.

Mapping the future

The AV Act, which received Royal Assent in November 2024 following its announcement in the King’s Speech, established a pioneering liability framework for autonomous vehicles.

Under the new law, motorists are protected from civil and criminal liability for collisions caused by software or hardware failures when their car is genuinely in self‑driving mode.

However, “secondary legislation” remains outstanding before the truly driverless operation is permitted.

At present, the UK allows “limited self‑driving” systems—such as advanced cruise control or lane‑keeping assistance—only if a licenced driver remains alert, in control, and ready to take over at any moment.

The DfT has told industry stakeholders it is working “quickly” to lay out the remaining regulations and will also explore short‑term trials and pilot schemes to foster a vibrant domestic AV sector.

 

 

On trial

Several technology firms are already testing sophisticated autonomous platforms on British streets.

Wayve, the Oxford‑based startup backed by investors including the Volvo Group, is conducting trials of its vision‑based AI in London and Manchester.

Uber, which operates robotaxi services in Arizona and Texas, has signalled its readiness to deploy similar fleets here once regulatory clarity arrives.

Meanwhile, Tesla has demonstrated its “Full Self‑Driving” software on European roads—most notably navigating 12 lanes of traffic around the Arc de Triomphe in Paris—though it has no firm UK launch date.

Progress and Pitfalls

Internationally, the legalisation of driverless vehicles varies widely.

In the United States, Nevada became the first jurisdiction to license fully autonomous cars in 2018, and California now hosts dozens of companies testing robotaxis under specific regulated frameworks.

Waymo and CruiseAVE have each logged millions of miles on public roads, though both have faced technical setbacks, including high‑profile collisions and software glitches.

China has its own AV fast lane: more than 20 cities, led by Shanghai and Beijing, allow unmanned taxi services from domestic giants Baidu and Didi Chuxing.

Singapore’s government has carved out dedicated testing zones for driverless buses and logistics vehicles, aiming to build public trust through incremental expansion.

However, global deployments have exposed persistent challenges.

Software algorithms excel in predictable, mapped environments but struggle with unstructured scenarios—construction zones, poorly marked roads or erratic pedestrian behaviour.

High‑speed driving on motorways presents a separate set of risks, particularly when vehicles encounter sudden obstacles or adverse weather conditions.

Safety, Trust and Infrastructure

Dr Saber Fallah, Professor of Safe AI and Autonomy at the University of Surrey, argues that Britain’s “cautious approach” is justified.

“We must move beyond statistical performance in controlled settings to ensure transparent decision‑making under the full spectrum of real‑world conditions,” he said. “Hybrid validation—combining formal methods with extensive simulation and live trials—must underpin any rollout.”

Professor Fallah also highlighted gaps in digital infrastructure.

“Reliable, low‑latency connectivity is essential for over‑the‑air updates and vehicle‑to‑infrastructure communication,” he noted. “Without a robust 5G and fibre backbone, vehicles could be stripped of critical support in urban canyons or rural stretches.”

Yet to be convinced

Not all players remain committed to a standalone robotaxi model.

General Motors’ Cruise unit, once a poster child for autonomous taxi services in San Francisco, was folded into GM’s broader Advanced Driver Assistance Systems (ADAS) division late last year.

The automaker cited the “immense time and resources” required to scale a dedicated robotaxi fleet amid intensifying competition.

Likewise, Ford and Volkswagen have curtailed separate AV lab efforts, opting instead for partnerships with technology startups to co‑develop self‑driving modules integrated into conventional vehicles.

Such collaborations aim to leverage existing dealership networks and maintenance ecosystems, smoothing consumer adoption.

 

 

The road ahead

With a regulatory roadmap now set for mid‑2027, industry observers say the next two years will be crucial.

The DfT must not only finalise comprehensive secondary legislation but also work closely with local authorities to designate suitable trial zones and establish liability protocols for data sharing and cybersecurity breaches.

Consumer advocates warn that public acceptance will hinge on transparent reporting of both successes and failures during early deployments.

“Driverless cars promise transformational benefits—improved road safety, reduced congestion and enhanced mobility for the elderly and disabled—but only if people trust them,” said Sarah Williams of the Transport Research Foundation.

As the UK stakes its claim to lead in autonomous vehicle regulation, balancing innovation with caution remains the watchword.

If the Government hits its revised 2027 deadline, Britain could join a select group of nations with fully legalised, truly driverless traffic—provided that the technology and the laws underpinning it keep pace with the promise.
