Drivers in Britain could be legally allowed to take their hands off the wheel to check their emails or read a newspaper in cars fitted with the latest technology ‘by the end of this year’, the Government has confirmed today.
In a statement issued by the Department for Transport, it said the first types of ‘self-driving’ vehicles fitted with Automated Lane Keeping Systems – or ALKS – could be permitted to steer themselves in slow moving traffic on motorways – but only at up to speeds of 37mph (60 kph) – before the end of 2021.
The update comes after a call for evidence launched by ministers in August to determine if the technology is safe to use on the road and what impact it could have on reducing fatalities, emissions and congestion.
However, insurers and safety experts have warned the Government over the misuse of terms such as ‘self-driving’ to describe ALKS, saying it could pose real dangers to road users if motorists become over-reliant on the systems, which may cause more accidents in the short term.
Government paves the way for hands-free driving to be legal on UK motorways: The Department for Transport has today announced it is to launch a consultation for how Automated Lane Keeping Systems and other ‘self-driving’ vehicle technology can be written into the Highway Code to ensure it can be used safely and responsibly by users
Today’s announcement says the Government has set out how ‘vehicles fitted with Automated Lane Keeping System (ALKS) technology could legally be defined as self-driving’.
However, it caveats that this is ‘only as long as they receive GB type approval and that there is no evidence to challenge the vehicle’s ability to self-drive’.
Designed only for use on a motorway, ALKS enables a vehicle to drive itself – including steering and managing the speed and distance to the vehicle ahead – in a single lane, while maintaining the ability to easily and safely return control to the driver within ten seconds in case of problems.
If the driver failed to act, the vehicle would come to a stop. Motorists would not be allowed to switch lanes while using the technology.
ALKS is classified by the UN as Level 3 automation – meaning drivers do not have to be in charge of the vehicle, but must be ready to take charge with warning.
While the system is operational, there is no requirement for the user to monitor the driving environment, meaning they could be allowed to undertake tasks such as sending a text message or watching a film – so long as they could easily re-take charge of the vehicle.
Currently, the highest level of vehicle autonomy being used on UK roads is Tesla’s Autopilot, which is classified as Level 2. If given the green light, Automated Lane Keeping Systems will be the first instance of Level 3 vehicle autonomy in the UK
Mercedes already has a system capable of Level 3 automation. Its ‘Drive Pilot’ system can be activated by the driver via controls on the steering wheel. The system uses a combination of cameras, radar and ‘Lidar’ (light detection and ranging optical sensors which measure distance and speed) along with precise Wi-Fi positioning and a high-definition digital map to ‘drive itself’
Models on sale in the UK already feature such technology, including the latest Mercedes-Benz models (like the
Tesla’s driver assistance mode, dubbed ‘Autopilot’, is only currently considered Level 2, however.
The DfT today says the introduction of the technology ‘could improve road safety by reducing human error’, which contributes to over 85 per cent of accidents.
Transport Minister Rachel Maclean said the Government is paving the way for ‘making future journeys greener, easier and more reliable’ by legalising the use of ALKS on motorways from this year
It will launch a consultation, which will conclude on 28 May, for new specific wording changes to the Highway Code to ensure clear rules dictate how the technology should be used safely and responsibly.
Transport Minister Rachel Maclean described it as a ‘major step’ for the safe use of self-driving vehicles in the UK, saying government is paving the way for ‘making future journeys greener, easier and more reliable while also helping the nation to build back better’.
However, she added: ‘But we must ensure that this exciting new tech is deployed safely, which is why we are consulting on what the rules to enable this should look like.
‘In doing so, we can improve transport for all, securing the UK’s place as a global science superpower.’
SMMT Chief Executive, Mike Hawes, also commented in the DfT’s official statement, but notably avoided the use of the term ‘self-driving’ and instead referred to ALKS as ‘automated systems’.
‘The automotive industry welcomes this vital step to permit the use of automated vehicles on UK roads, which will put Britain in the vanguard of road safety and automotive technology,’ he said.
‘Automated driving systems could prevent 47,000 serious accidents and save 3,900 lives over the next decade through their ability to reduce the single largest cause of road accidents – human error.
‘Technologies such as Automated Lane Keeping Systems will pave the way for higher levels of automation in future – and these advances will unleash Britain’s potential to be a world leader in the development and use of these technologies, creating essential jobs while ensuring our roads remain among the safest on the planet.’
While ALKS is functioning there is no requirement for the user to monitor the driving environment, meaning they could be allowed to undertake tasks such as sending a text message or sending emails – so long as they could easily re-take control of the vehicle
Insurers and safety experts have shared their concerns that customers might misinterpret today’s lower levels of driver assistance as full automation, potentially causing more accidents in the short term
Experts warn: Referring to cars with ALKS as ‘self-driving’ will lead to misuse
While the Government looks set on accelerating its plans to allow hands-free driving on UK roads, motor insurers and vehicle safety experts have warned both car makers and government regulators not to ‘inappropriately’ refer to systems such as ALKS as ‘self-driving’ tech.
They are worried customers might misinterpret today’s lower levels of driving assistance as full automation, potentially causing more accidents in the short term and permanently damaging public confidence in the technology.
‘What you describe things as is incredibly important, so people don’t use them inappropriately,’ said David Williams, managing director of underwriting at AXA Insurance, whose parent AXA SA sold €17 billion worth of property and casualty insurance, including motor insurance, in 2020.
‘I genuinely believe the world will be a safer place with autonomous vehicles and I really don’t want that derailed,’ he added.
Mark Shepherd, head of general insurance policy at the Association of British Insurers, said: ‘While the insurance industry fully supports the development towards more automated vehicles, drivers must not be given unrealistic expectations about a system’s capability.
‘It is vital that Automated Lane Keeping Systems (ALKS), which rely on the driver to take back control, are not classed as automated, but as assisted systems. By keeping this distinction clear we can help ensure that the rules around ALKS are appropriate and put driver and passenger safety first.’
The warning from motor industry insiders comes following the reports last week of
It is believed the owner had driven the car out of his driveway then jumped out of the driver’s seat and into the backseat – where he was found dead – after engaging the ‘Autopilot’ system. The other man was in the passenger seat.
Experts list ‘non-negotiable’ criteria for ALKS to meet
Thatcham Research and the ABI believe there are four non-negotiable criteria that need to be met before ALKS can be classified as automated:
1. The vehicle must have the capability, and be allowed through legislation, to safely change lanes to avoid an incident
2. The vehicle must have the capability to find a ‘safe harbour’ at the side of the road and not stop in a ‘live’ lane
3. The systems on the vehicle must be able to recognise UK road signs and this needs to be assured by an independent organisation
4. Data must be made available remotely through a neutral server for any incident to verify who was ‘in charge’ at the time of the incident – the driver or the vehicle
Tesla’s Autopilot is deemed Level 2 on the automation scale, which requires the user to ‘remain engaged with the driving task and monitor the environment at all times’.
However, the fatal episode in the US has triggered a number of people to
Insurers warn that regulations in the Americas, Europe and Asia lag far behind technical developments with these automated driving systems – and as a result, issues over accident liability are unclear.
Some experts say ALKS should be called ‘assisted-driving technology’ to avoid potentially misleading consumers into believing they can let their attention wander at the wheel.
Britain’s Thatcham Research, which has been
‘If this technology was really automated and could do what you or I could do, insurers would welcome it,’ said Matthew Avery, Thatcham’s research director.
He said incorrect terminology and marketing of ALKS will lead to confusion, unnecessary crashes, and potentially injuries or fatalities.
‘There is still a lot of work needed though by both legislators and the automotive industry before any vehicle can be classed as automated and allowed safely on to the UK roads,’ Avery explained,
‘Automated Lane Keeping Systems as currently proposed by the Government are not automated. They are assisted driving systems as they rely on the driver to take back control.
‘Aside from the lack of technical capabilities, by calling ALKS automated our concern also is that the UK Government is contributing to the confusion and frequent misuse of assisted driving systems that have unfortunately already led to many tragic deaths.
‘A widespread and effective ongoing communications campaign led by the automotive industry and supported by insurers and safety organisations is essential if we are going to address current and future misconceptions and misuse.’
Daimler, the parent company of Mercedes-Benz, has been a pioneer of self-driving technology and is seeking global regulatory approval for its ‘Level 3’ Drive Pilot system.
In an email to Reuters, Daimler called the Drive Pilot system ‘conditional automated driving’ and avoided the term ‘self-driving’.
How Mercedes’ hands-free driving tech works
Mercedes’ new S-Class luxury limo features the Level 3 Drive Pilot system. Here’s how it functions…
1. Driver activates Drive Pilot system using controls on steering wheel rim (on either side above the thumb recesses).
2. Powerful central on-board computer controls car’s speed and distance and coordinates input from cameras (including in rear windscreen), radar, sensors, sat-nav and digital mapping to keep self-driving car safely on track.
3. Precise wi-fi positioning and constantly updating high-definition digital map help car monitor its positon to ‘drive itself’. Receives information about the road lay-out, route, traffic signs and accidents or roadworks.
4. Cameras, radar and Lidar sensors (light detection and ranging optical sensors) measure relative distance and speed of car, other traffic, signs and road conditions to keep car in lane and a safe distance from other vehicles. Lidar also spots flashing emergency vehicle lights. Image processing uses technologies from the world of artificial intelligence.
5. System recognises unexpected traffic situations – accidents and jams – and deals with them autonomously by evasive action or braking. A built-in microphone also picks up of emergency vehicle sirens.
6. All algorithms are calculated twice for safety.
7. Level 3 autonomy in ‘conditionally automated mode’.
8. Currently ‘self-drive speed’ limited to 37 mph (60 km/h) but that set to rise as proposed new self-drive legislation introduced.
9. If driver fails to take back control (or purpose or after collapsing at wheel) car gives increasingly urgent visual and sound prompting. If warnings are ignored, Drive Pilot system automatically applies the brakes to bring vehicle to controlled standstill. It also activates car’s hazard warning lights and emergency call system, unlocking doors and windows for emergency services.
10. Drivers prompted to take back control when vehicle approaches end of a designated self-driving route – or encounters changing conditions such as a tunnel, bad weather or changing traffic. Driver can deactivate Drive Pilot self-drive system any time without prompting.
‘This is a paradigm change, because the vehicle takes control,’ Daimler said. ‘The driver can turn away from what is happening on the road’ to surf the internet, or enjoy ‘a relaxing seat massage,’ it added.
AXA’s Williams attended a presentation of Drive Pilot to the Association of British Insurers last year.
‘It is absolutely amazing, but it is driver assistance,’ he said, and ‘not full automation’.
Neil Ingram, insurer Direct Line’s head of motor product management, said it was vital ‘Level 3’ technologies were described clearly and accurately.
‘We’ve known for years the path to full automation was a tricky one and Level 3 has always been the problem child,’ he said.
‘If the Government decides to designate ALKS systems as automated then that makes it very, very real.’
The AA’s president, Edmund King, believes ALKS should be classified as ‘Assisted Driving’ technology, saying it is ‘a world away from self-driving’.
He added: ‘Without doubt vehicle safety technology can save lives, but we shouldn’t be in race to take drivers’ hands off the wheel.
‘There are still gaps in how this technology detects and stops if the vehicle is involved in a collision. There are still question marks over how drivers will be fully informed how these systems work. More needs to be done to rigorously test these systems before they are used on UK roads.’
Anthony Smith, CEO of independent UK consumer watchdog Transport Focus said that, with proper consumer education, ALKS ‘could help in slow moving traffic’ but warned the even the word ‘automated’ needs ‘careful testing’ to understand if drivers would use technology in the correct way.
Commenting on the DfT’s announcement, Jim Holder, editorial director at What Car?, said: ‘Revising the Highway Code to take into account self-driving technology is an important first step in having the right legislative framework in place to allow driverless testing and driverless vehicles to operate on UK roads.
‘However, past events have shown just how important it is to ensure customers and drivers understand the limitations of the technology, and do not confuse driver assistance systems or semi-driverless technology with a fully autonomous feature.
‘The Government’s plans are ambitious, suggesting we could see driverless cars mixing with actual traffic already later this year.
‘The legislative framework should always place vehicle and passenger safety as a priority, and not industrial development.’
He added: ‘It’s important that the UK stays at the forefront of this emerging technology, but also in a manner that always prioritises understanding of the technology for its users.’
In 2018, a pedestrian was killed by an Uber self-driving car. The death of Elaine Herzberg, 49, in Arizona was the first on record involving such a vehicle.
Uber halted its testing of the technology following the incident. At the time of the crash it was claimed the car’s ‘safety driver’ was watching TV.
In 2016, a 40-year-old driver in Florida was killed in a Tesla on autopilot that failed to stop when a tractor-trailer made a left turn in front of it. The National Highway Traffic Safety Administration in the US has opened around 28 investigations into crashes of Teslas that may have involved self-drive settings.
Steve Gooding of the RAC Foundation said humans were ‘invariably the weak link’ and added: ‘There is a risk of situations in which drivers over-rely on the automated system, expecting it to deal with events for which it is neither intended nor capable.’
It is understood the proposals will not require a change in the law as they are covered by the Automated and Electric Vehicles Act 2018. Car-makers will have to meet new safety requirements for vehicles to be legally registered. The Highway Code will also be updated.
What is ALKS and how does it work?
Automated Lane Keeping System (ALKS) technology would be the most advanced car automation so far seen on UK roads.
When activated, the ALKS keeps the vehicle within its lane, controlling its movements for extended periods of time without the driver needing to do anything.
However, the driver must be ready and able to resume driving control within seconds if prompted by the vehicle.
Different manufacturers all have their own systems, but generally it involves a forward-looking camera, usually behind the windshield, laser sensors, infrared sensors and radar sensors to detect if you’re unintentionally drifting out of lane.
When the sensors detect the car is moving out of lane, it can automatically apply braking to one side of the vehicle to correct the vehicles position in the road.
Rather than subtle braking, some systems can use discreet steering interventions.
ALKS is designated a Level 3 system by the UN’s Economic Commission for Europe.
This signifies that the person at the wheel is not driving when the automated systems are engaged, but can step in at any time and must take over at the system’s request.
With a Level 3 system activated, the user is allowed to do other things, such as watch a movie or even send a text message, but must retain some level of alertness to what is happening around them.
There are five stages of autonomy for self-driving cars, with Level 5 being full autonomy.
While it is similar to the technology already being used by Tesla, which it calls Autopilot, the US firm’s system is only deemed Level 2 – where drivers are expected to keep their full attention on traffic.
Lane Keeping Assist – a function that’s been available in new cars for over a decade – is also deemed to fall into Level 1 and 2 because it only alerts the driver that they are veering out of their lane and it is up to the user to steer the vehicle.
