The challenge of London: can driverless cars unblock the world’s sixth most gridlocked city?

Today’s two new statements from the London Assembly – one on the cost of congestion and the other on changes to the licensing guidelines for taxis and minicabs – have highlighted major transport problems in the capital… issues which connected and autonomous vehicles (CAVs) could potentially help to solve.

Caroline Pidgeon MBE AM, chair of the London Assembly Transport Committee, said: “The revelation that London is the sixth most gridlocked city in the world, behind Moscow, Istanbul, Bogota and Mexico City, will come as no surprise to most road users.
“This is a shockingly expensive fact and hugely damaging to our global reputation. Getting millions of Londoners to and from work every day is a massive challenge – but we really have to try harder for the sake of our economy and our environment.
“The need to improve London’s public transport capacity is desperate – hence the urgent necessity for Crossrail and for more people to walk and cycle whenever possible.” 

Notably, the Transport Committee’s 65-page 2017 report London Stalling described the current Congestion Charge as “no longer fit for purpose” and recommended that “the Mayor should make plans now to introduce road pricing.”

Transport data firm Inrix has since calculated that the average road user in London lost up to £1,680 last year due to traffic jams.

There’s little doubt that smart highways and connected cars could help to ease congestion, or that electric vehicles would cut the damage from tailpipe emissions.

Admittedly, Adam Millard-Ball’s concern that self-driving cars could exacerbate the problem by cruising to get around paying for parking (as outlined in A dystopian vision of polluted London) would need to be tackled.

As to the government’s proposed new licensing guidelines for taxis and minicabs – which would require cabbies to pass enhanced criminal record checks – Pidgeon said: “Anything that improves the safety of passengers has to be a good thing.
“We need to prevent the likes of John Worboys from being able to operate as a legitimate licensed driver again and stop the worrying numbers of sexual assaults in minicabs.
“The big miss in the government response to the Department for Transport (DfT) Review is the statutory definition of plying for hire not being resolved. This has long been a major bone of contention and it appears to be too hard to resolve, so they aren’t going to try.”

Under existing regulations, private hire vehicles (PHVs) may only pick up passengers when pre-booked, rather than from a rank or being hailed.

However, the RMT, the union for transport workers, asserts that: “ smartphone apps such as Uber are circumventing the law governing the taxi and minicab industry”.

If the authorities haven’t even got their heads around smartphones yet, they’ve certainly got a lot of thinking to do when it comes to driverless cars, not least the thorny issue of who to save in no-win crash situations.

CASE study: connected, autonomous, something and electric

The motor industry is notoriously fond of an acronym and here’s a new one which might just catch on: CASE.

In this case, C stands for connected, A for autonomous and E for electric, but there’s disagreement about what the S should stand for.

Vehicle manufacturer Daimler goes for connected, autonomous, shared and electric, although if you dig a bit deeper into their website they keep their options open with “shared and services”.

“Each of these has the power to turn our entire industry upside down,” said Dr Dieter Zetsche, chairman of the board of Daimler AG. “But the true revolution is in combining them in a comprehensive, seamless package.”

Over at car parts maker ZF, Andy Whydell, vice president of systems product planning for active and passive safety, goes for connected, autonomous, safe and electric.

For explanations of other vehicle-related terms and acronyms, see our Cars of the Future glossary.

Personal space: inside cars of the future

While navigation tech and crash ethics grab a lot of future car column inches, the implications for interiors deserve more attention.

As Marek Reichman, Aston Martin’s chief creative officer, noted at the launch of the Lagonda Vision Concept last year: “The electrification revolution means there is no longer any need for ‘horse and carriage’ design. The batteries occupy the floor of the car. Everything above that line belongs to us.”

Combine that with driverless and the options become mindboggling. From self-driving emergency clinics to mobile restaurants or red light districts on wheels, solutions will doubtless be designed for a wide range of activities.

Beyond the ‘real’ world, of course, there are further possibilities. Two former Audi employees, Nils Wollny and Marcus Kühne, set up Holoride to “develop the future of in-vehicle media”.

One innovation involves using live vehicle data (e.g. on acceleration or steering) to prompt real-time feedback in a virtual reality environment. They say this provides a more immersive experience and can also help to reduce motion sickness.

Reasons to fear driverless cars: job losses, personal data and who to save

Despite recent surveys showing a growing appetite for driverless technology, reports of rocks being thrown at self-driving test cars in Arizona demonstrate that public support is far from universal.

The Ford Trends Report for 2019 found that 67% of adults globally would rather have their children ride in a self-driving vehicle than ride with a stranger.

However, Arizona Central has highlighted at least 21 incidents involving autonomous vehicles, including, in the most extreme example, a handgun being pulled on a Waymo safety driver.

Job losses

According to Phil Simon, information technologies lecturer at Arizona State University, the discontent stems from a belief that Waymo will put them out of a job.

“There are always winners and losers, and these are probably people who are afraid and this is a way for them to fight back in some small, futile way,” he said.

In the UK, research by MoneySuperMarket found that over a million jobs could be replaced by driverless vehicles , including those of delivery, forklift, bus and taxi drivers.

Personal data

Another common objection to self-driving cars relates to data access.

According to a survey by insurer AXA and law firm Burges Salmon, just 5% of motorists said vehicle manufacturers should control driverless car personal data.

20% said the government should be the data controller, while 16% said a new driverless car regulatory body should be created.

David Williams, technical director at AXA UK, said: “Connected and autonomous vehicles (CAVs) will only become a reality if users trust us with their personal data. This data is integral for driverless vehicles to provide reduced congestion, fewer accidents and better mobility for all.”

Civil liberty advocates will have read with interest the Associated Press finding that major automakers are providing live data to Chinese authorities.

Those listed include Tesla, Volkswagen, BMW, Daimler, Ford, General Motors, Nissan and Mitsubishi.

Chinese officials say it is for analytical purposes to improve public safety and infrastructure planning, but this is a country where things like internet censorship and facial recognition are commonplace.

Who to save

Another thorny issue is the question of who to save in a crash situation – see the section on The Trolley Problem in Autonomous now: the shift to self-driving.

According to The Moral Machine, an experiment involving two million users in more than 200 countries, most people agree that:

1) Humans should be saved over animals.
2) The lives of the many should be prioritised over the few.
3) The young should have priority over the old.

Unfortunately, it isn’t that simple. The World Economic Forum reported some peculiar preferences e.g. dogs should be prioritised over criminals and cats.

Will all manufacturers apply the same default settings? Should owners be able to change them? Many would surely be tempted to protect themselves over all others.

The debate looks set to run and run.

Autonomous now: the shift to self-driving

This article, a version of which first appeared in the July 2018 issue of IMI Magazine, was the spark for Cars of the Future. IMI editor, Tim Kiek, said: “I’ve featured articles on autonomous vehicles throughout my tenure but never one which explores the topic with such forensic rigour.”

Autonomous Now… Neil Kennett explores blockbuster themes in the shift to self-driving

In our May issue, Traka’s Paul Smith outlined the six levels of autonomy, detailed how Audi’s A8 and Tesla’s Model S are already around Level 3, and noted that driverless motoring could be a reality on UK motorways by 2021.

Let that sink in for a moment. 30 years ago, this was the stuff of science fiction. Gen X children across the world dreamt of owning KITT from Knight Rider – a talking, self-driving, bulletproof Trans-Am. For many, that dream will nearly come true.

While the leaders in this new wave of cars are ready to roll, a few thorny hurdles stand in their way: the elimination of digital ‘not-spots’; devising a new liability framework; meeting the challenges of a mixed (autonomous and non-autonomous) car parc; and addressing legitimate cybersecurity and ethical concerns.

Then there’s the skills shortage in intelligent mobility; data governance issues; what all this means for those who actively enjoy driving; and the impact on other road users.

Before investigating out how we might get from A to B in just three years, let’s get the acronym sorted. For the purposes of this article, we’ll call them connected and autonomous vehicles, CAVs.

Now for a definition: According to The Institution of Mechanical Engineers, when the term autonomy is applied to a car, it refers to decisions taken by embedded intelligence in the vehicle systems.

This is rules-based software. For example, if the forward-facing camera image contains a pixel pattern associated with a car, and the radar confirms this, and a collision is predicted, then a solution will be deployed, such as emergency braking.

Relentless progress

If I had asked people what they wanted, they would have said faster horses,” Henry Ford is often quoted as saying. Vehicle manufacturers (VMs) have been pushing the envelope ever since.

A cautionary tale comes from Dan McComas, former senior vice-president for product at Reddit, who witnessed “…a complete breakdown in the kind of thought process behind how your technology is going to affect the users that use it and the world at large.”

VMs and tech giants cite many attractive benefits in shifting to self-driving: increased mobility, improved road safety and reduced congestion.

However, the excellent 2017 House of Lords Science and Technology Select Committee report, Connected and Autonomous Vehicles: The Future?, pointed out: “While we cannot say with any certainty what the impact on congestion will be, it is possible to imagine a situation of total gridlock… while some of our evidence has suggested that CAV could have huge economic benefits, we are not convinced that the statistics provided have been properly substantiated.”

That’s a lot of uncertainty, but the committee also heard compelling evidence in support of CAVs, not least the Association of British Insurers submitting that human error is a causal factor in 90-95% of road traffic accidents.

That stat originates from the US and some claim the UK figure is lower. Here, there were 27 road deaths per million inhabitants in 2017, a 5% year-on-year improvement. Within the EU, only Sweden had a better record. The point stands: humans are fallible.

The BBC’s Tomorrow’s World boldly stated: “Over a million people are killed worldwide each year by cars, with 90% of accidents caused by human error. Several million miles of test drives have shown driverless cars to be safer.”

One firm advocate is Antonio Avenoso, executive director of The European Transport Safety Council. “We are calling for safer vehicle standards such as mandatory fitment of automated emergency braking and intelligent speed assistance; better infrastructure safety rules and a solid framework for the safe rollout of automated driving,” he said.

Bob Lutz, former vice chair of General Motors, is more caustic. “Human drivers are distracted. They drink. They text. They take drugs. Autonomous vehicles do none of that,” he said.

Further to the safety argument, there’s cold hard cash. Morgan Stanley has estimated that autonomous cars could save the US $1.3 trillion annually through lower fuel consumption ($169bn), reduced crash costs ($488bn) and productivity increases ($645bn).

In the UK, a 2015 joint report by KPMG and the SMMT, Connected and Autonomous Vehicles – The UK Economic Opportunity, estimated socio-economic benefits “in the region of £51 billion per year by 2030”, if we consolidate a leadership position. Most of this weighty sum is predicted to come from increased ease of travel, fewer accidents and improved productivity.

Other key findings were that CAVs could create an additional 320,000 jobs in the UK by 2030, 25,000 of which would be in automotive manufacturing, and that CAVs could save over 2,500 lives and prevent more than 25,000 serious accidents in the UK by 2030.

“Already more than half of new cars sold are available with at least one semi-autonomous driving feature,” said SMMT chief executive, Mike Hawes.

It should certainly be a good time to be in the sensor business. ABI Research forecasts that as many as 36 million LiDAR units will ship in 2025, with a market value of $7.2bn.

 A recent study by The University of Greenwich found that 43% of 925 respondents “felt positive” towards the concept of CAVs. 46% were undecided, with road safety (51%) and cybersecurity (44%) their primary concerns.

Cyber threats

These concerns are not without foundation. In a series of experiments from 2013 onwards, Charlie Miller and Chris Valasek showed that a hacker with wired or over-the-internet access to certain vehicles could disable or apply the brakes, turn the steering wheel and cause acceleration.

“No matter what we did in the past, the human had a chance to control the car,” said Miller. “But if you’re sitting in the back seat, that’s a whole different story. You’re totally at the mercy of the vehicle.”

While a malicious attack could have horrific consequences, Craig Smith, a security researcher who runs Car Hacking Village at Defcon, the world’s largest hacking convention, believes CAVs are generally more secure.

“They have to use lots of different sensors,” he explained. “The interesting thing is that each sensor doesn’t trust the other. It’s closer to the way humans figure out whether something is an illusion or not. And that’s harder for a hacker to deal with.”

What if a CAV owner wanted a trusted third party to gain access, an independent workshop, for example? The aftermarket received a boost from The European Parliament in March, when 633 MEPs requested that the European Commission publish a legislative initiative to guarantee fair, unrestricted and in real-time access to in-vehicle data before the end of the year.

Level 3 tipping point

The halfway stage of automation, dubbed Level 3 or Conditional Assistance, is pivotal. These vehicles can monitor their surroundings, change lanes, and control steering and braking, but the driver must be ready to take back control if required.

To illustrate the current state of play – how these are no longer theoretical conundrums but real world problems – news broke in April of a very modern dangerous driving incident.

A driver who put his Tesla into autopilot and moved into the passenger seat while at 40mph on the M1 was disqualified for 18 months after footage was posted online. Bhavesh Patel admitted that what he had done was “silly”, but insisted his car was “amazing”.

PC Kirk Caldicutt, of Hertfordshire Police, said: “What Patel did was grossly irresponsible and could have easily ended in tragedy. He not only endangered his own life but the lives of other innocent people using the motorway. This case should serve as an example to all drivers who have access to autopilot controls. I want to stress that they are in no way a substitute for a competent motorist in the driving seat who can react appropriately to the road ahead.”

Professor Neville Stanton, of the University of Southampton, has highlighted that, in simulated emergencies, up to a third of drivers of automated vehicles did not recover the situation, whereas almost all drivers of manual vehicles were able to do so.

Further still, CAV drivers took, on average, six times longer than manual drivers to respond to the emergency braking of other vehicles. “This is particularly true if they are engaging in other activities, such as reading, answering emails, watching movies or surfing the internet,” he said.

Steve Gooding, Director of the RAC Foundation, expressed concern that a Level 3 vehicle could hand back control to a driver who “might well be asleep at the time”. He suggested the risk could be managed by skipping this level and requiring CAVs to be capable of coping with any eventuality.

Who to save?

 Unfortunately, in many crash situations, there is no win-win; it’s a case of the least worst option. Which brings us to ethics, and a thought experiment called The Trolley Problem.

The scenario is this: There is a runaway trolley and, ahead, five people are tied to the track. You are standing some distance off, next to a lever. If you pull it, the trolley will switch to a track only one person is tied to. What do you do?

Referring to our definition, CAVs work on rules, which must be coded. In surveys published in the journal, Science, researchers in the US and France set out to canvas opinion on how driverless cars should behave in no-win situations.

76% agreed that a driverless car should sacrifice its passenger rather than kill 10 pedestrians. The pinch came when they were asked if they would rather purchase a car programmed to protect them instead of pedestrians.

The waters get murkier still. If regulations forced manufacturers to install moral algorithms that minimised deaths, the majority of respondents said they’d buy unregulated cars instead, potentially undermining the much-vaunted safety benefits.

One of the report’s authors, Azim Shariff, of the University of Oregon, commented: “Would you really want to be among the minority shouldering the duties of safety, when everyone else is free-riding, so to speak, on your equitability?”

Alan Winfield, of the Bristol Robotics Laboratory, added: “Without transparency you cannot regulate, and without regulation, driverless cars are unlikely to be trusted. There’s a strong case for a driverless car equivalent to the Civil Aviation Authority.”

Public perceptions

What’s needed, of course, is more testing, but a fatal crash involving an Uber test vehicle in March did little to advance that cause.

In a recent survey of consumer attitudes, the American Automobile Association found that 73% would be too afraid to ride in a self-driving car, up from 63% in the previous survey. The biggest slip in confidence was among millennials.

In Arizona, where the crash happened, the previously supportive Governor, Doug Ducey, suspended Uber’s testing. In Minnesota, Senator Jim Abeler set about drafting legislation to ban automated driving systems until the companies behind them can prove they’re safe.

Harald Proff, of Deloitte, commented: “The US is in no way reckless when it comes to autonomous driving tests, but in Europe, and especially in Germany, rules are a notch stricter when it comes to putting cars on public streets.”

Indeed. A flagship project in Berlin involves four autonomous buses ferrying doctors and staff across the private grounds of the city’s Charite hospital, along pre-defined routes, away from public streets, at a maximum 12mph.

Here, roads minister Jesse Norman announced a three-year review of driving laws – an “extensive regulatory reform programme” intended to ensure “the right laws are in place before the widespread use of these vehicles on UK roads”. In the meantime, public tests continue.

 On UK roads

 Early UK road trials include: The GATEway Project in London; Venturer in Bristol; and UK Autodrive in Milton Keynes and Coventry.

GATEway is entering its final phase, which will see a fleet of driverless pods providing a shuttle service around a 3.4km route on the Greenwich Peninsula. In a world first, members of the public are invited to take part in the research, by riding in or engaging with the pods and sharing their opinions.

Developed by British companies Westfield Sportscars and Heathrow Enterprises, and powered by Fusion Processing technology, the pods have no steering wheels or typical driver controls.

Venturer has so far published the results of two trials involving a Wildcat road vehicle. The first – to understand handover of control between vehicle and driver – concluded that the functionality should “proceed with caution”.

The second – to consider how CAVs interact with other road users and junctions – suggested that making them drive more cautiously than the average human driver could create a traffic calming effect, resulting in safety and congestion benefits.

UK Autodrive, with partner Jaguar Land Rover, has sought to address the fact that, in times of heavy congestion, up to 30% of traffic consists of vehicles looking for parking spaces.

“In the future, connected features will alert drivers to empty spaces and autonomous vehicles will be able to drive straight to them,” said Tim Armitage, Arup’s UK Autodrive project director.

“Valet parking systems will enable autonomous vehicles to drop passengers at convenient points, after which the vehicle will leave by itself to undertake a further journey, or park out-of-town. As well as making parking less of a hassle, these new ways of parking and drop-off will allow cities to radically redefine their use of space, with far less land potentially needed for parking spaces.”

In February, Highways England announced the HumanDrive Project to undertake “the most complex journey across the UK, without driver input”, taking in country roads, high speed roundabouts, A-roads and motorways.

Business and Energy Secretary, Greg Clark, commented: “Low carbon and self-driving vehicles are the future and they are going to drive forward a global revolution in mobility. This revolution has the potential to be worth £52bn to our economy by 2035, and the opportunity to be at the forefront of this change is one we cannot afford to miss.”

In April, the Driven consortium, which is in receipt of an £8.6m government grant, unveiled its plan to run a fleet of Level 4 vehicles in urban areas and on motorways.

Level 4 CAVs might occasionally ask for a manual input, but will continue self-driving if they don’t get one. The project will culminate in journeys between London and Oxford in 2019.

Give us a date

 So, if Level 4 testing goes to plan next year, when can we expect Level 5, full automation? Bloomberg New Energy Finance asked 300 automotive, energy and technology executives to name the year when US consumers will be able to buy a Level 5. Nearly 75% predicted the milestone won’t be reached before 2030. Suddenly, that sounds quite conservative.

Carrie Morton, deputy director of Mcity, the University of Michigan’s purpose-built test facility for CAVs, was more precise. “You’re going to see in the next couple of years isolated pilots of shared, automated Level 4 vehicles,” she said.

“And the distinction between Level 4 and Level 5 is that Level 4 have to operate in a very specific operating domain – it can only go certain places. You’re going to see that really soon. All the while the personally-owned vehicles you and I drive are going to have increasing levels of automation.”

As IMI CEO, Steve Nash, noted in the April issue of this magazine: “It requires around 2.5 terabytes of data to enable an A380 Airbus to fly autonomously across the Atlantic, whereas 45 terabytes of data are required to equip a Level 4 autonomous car to handle routine driving tasks.”

Is this an achievement comparable with putting a man on the moon? No. Is it as ground-breaking as the invention of the motor car itself? Probably not. It is simply progress. In the next decade, humans could set foot on Mars. Here on earth, cars will no longer need drivers.
