Black Cabs vs Robotaxis: Inside London’s £42bn Driverless Taxi Race

The black cab is the most reliable street furniture in London. It has passed hansom carriages, two world wars and the rise of Uber. But commerce now faces an adversary that cannot threaten with the beep of the horn, an artificial intelligence that travels two million miles a week and never learns a single street word.

In a quiet corner of Westminster, just behind Parliament Square, a Jaguar I-Pace roars around a roundabout full of tourists. The wheel turns, the indicators flash on and off, the speed is carefully monitored. The man sitting in the driver’s seat is not driving. Alex Kendall, CEO of British self-driving start-up Wayve, has his hands in his lap.

A few miles to the east, in a quiet testing room at Transport for London, Steven Fairbrass sits on his twentieth attempt at Knowledge of London. He has been studying for eight years. He stumbles on the street name of Portland Place and the inspector, kindly, tells him to come back another day.

These two scenes highlight the future of London’s transport and create the most important business case the capital’s roads have seen in a generation. The world’s most regulated taxi trade is at odds with one of the world’s most lucrative pieces of artificial intelligence, and the clash will change everything from city property values ​​to the United Kingdom’s industrial plans.

A trade that is already in reverse

The numbers tell their own sad story. There were 25,538 licensed black cab drivers in London in 2014. By November 2024 the number had dropped to 16,965, an average of more than a third in ten years. At the same time the number of licensed private hire drivers, Uber, Bolt, Addison Lee and others, grew by 82 percent, to 107,884. As Business Matters has previously explained, lost fares run into hundreds of millions of pounds a year, and the cost base of trade, electric vehicle financing, congestion charging, insurance, keeps rising.

The pipeline of new cabs is burning faster than existing employees are retiring. The Knowledge pass rate, the test that has for 161 years separated the “knowledge boys” from the rest, dropped from 59 percent in 2020 to 38 percent in 2025. Steve McNamara, the head of the Licensed Taxi Driver’s Association, warned that without intervention there could be a trade.

Into this soft market come two competitors with very different business models but with similar ambitions.

Silicon Valley meets the South Circular

Waymo, Alphabet’s autonomous driving arm, has been quietly mapping a 100-square-mile patch of London since the fall. A fleet of around 100 Jaguar Paces, equipped with the company’s proprietary stack of 29 cameras, six radars and five lidar units, has been filming the curious right-hand drive cityscape. The company, as Business Matters reported earlier this year, is targeting a fully driverless commercial launch in the fourth quarter of 2026, in partnership with fleet operator Moove.

Waymo’s CEO, Tekedra Mawakana, points to a ship that has flown more than 170 million paying passengers in the United States and a safety record that, the company says, shows 92 percent fewer accidents than a human. “We travel over two million miles a week,” he recently told Anderson Cooper in a CBS Minutes piece. “People drive about 700,000 kilometers in a lifetime, so this is about three lifetimes a week that our fleet drives.”

Wayve, a Cambridge-founded scale backed by Microsoft, Nvidia and now Uber, is deliberately taking a different approach. Its AI Driver is a basic model trained from the ground up with millions of hours of video, designed to adapt to any city rather than relying on the pre-built high-definition maps favored by Waymo. Betting is less, faster and, in theory, more efficient. It was enough to attract $1bn in funding last year and an $8.6bn valuation, the richest yet awarded to a British AI company. In May, Wayve signed a Memorandum of Understanding with the Department of Commerce and Industry to accelerate the path from test fleets to commercial deployment.

The prize is not just London fare. Ministers estimate that the private car sector could add £42bn to the UK economy and create close to 40,000 jobs by 2035. Whoever wins London, the most complex, highly regulated and highly monitored area of ​​urban driving in the western world, wins a benchmark that cannot be traded in all other currencies.

First control gun

For many years, Britain’s self-driving question was theoretical. The Automated Vehicles Act 2024 resolved the legal construction, creating a new category of “authorized self-driving business” that becomes liable when the vehicle is in charge. In a major move, the Department of Transportation has introduced an Automated Passenger Services program that is slated to arrive in the spring of 2026, allowing taxi and bus drivers to drive without a safe driver on board. The Vehicle Certification Agency has been certified as the sole national watchdog that determines which vehicles can carry paying passengers.

This is important for trade because permits, not technology, were the problem. Now the way is clear. Uber, in partnership with Wayve, plans to roll autonomous vehicles into its existing London app. Bolt indicated that he would follow. Waymo’s pilot may not carry a driver at all from day one. In twelve months, a Londoner may hail a robot on the same screen they use to call a human.

A human trench

The cabbies’ objection is not that the technology will fail. That a trip to London is not a problem to travel.

The experience requires novice drivers to memorize around 25,000 streets and 20,000 points of interest within a six-mile radius of Charing Cross. Tom Scullion, who has been driving for 34 years, says he is often asked to ride unaccompanied children to school and a regular Irish wolfhound to the vet. Trust is a function of license, and license is a function of years of learning.

And it is a biological function. Research by the late Professor Eleanor Maguire at University College London famously showed that the posterior hippocampus, the brain’s cabinet for filling spaces, grows larger in trained cabins. New work from UCL’s Spatial Cognition Group suggests, surprisingly, that taxi drivers’ route-planning techniques may inform the next generation of AI travel systems, a paradox not lost on commerce.

Whether that biological niche translates into trade protection is a key question for the board. Wayve and Waymo do not claim to be better navigators. They consider themselves cheaper, more readily available and, they argue, safer. In a city where the average fare for black cabs has risen sharply with the financial cost of an electric car, price competition is a threat that commerce has little response to.

What does it mean for UK plc

The important question isn’t whether the cabbie survives, it’s what the disruption tells us about Britain’s willingness to tolerate one. The Treasury is banking on the acquisition of AV to boost productivity and revive UK car production. The National Wealth Fund is reportedly close to backing Oxford’s driverless Oxa. Sherbet London recently raised £40m to electrify its fleet of black cabs, an obvious defensive play. Insurers, ship operators, mapping companies and local councils are all being asked to set an example that did not exist eighteen months ago.

Three commercial results stand out. The first is that London is treated by the biggest AV companies in the world as a proving ground; success here unlocks a passport control to Paris, Berlin and Tokyo. The second is that the United Kingdom, almost unique among major economies, has both a loyal domestic champion in Wave and a willing regulator, which is a rare resource in a sector dominated by American capital. The third is that the “Uberisation” that has been feared in the taxi industry, in retrospect, was a soft thing. The next disruption removes the driver entirely, along with the main cost line, the main appeal of customer service and, to a lesser extent, the main employer of working-class Londoners who never went to university.

The black cab will not disappear overnight. The same regulatory framework that accepts Waymo also guarantees a secure status for the taxi trade to get hired on the road, and the icon remains commercially important: all the tourism boards in the world can pay to keep TX5 in the established state. Sherbet’s investors, apparently, agree.

But economics is unforgiving. The number of “appearances” booked on TfL each year is falling. The capital cost of a new London-style electric cab now exceeds £70,000. And the next generation of would-be cabinetmakers, including 41-year-old Science graduate Anshu Moorjani, are entering a market where their newly grown hippocampi will be competing with fast-learning neural networks every week.

A century after the last horse-drawn hansom left London’s streets, the city is preparing to host Europe’s first robotic service. Experience has made the London cab the gold standard of urban transport. Whether it survives the algorithm is now, ultimately, the ultimate question.
