We are currently witnessing a pivotal shift as car manufacturers collaborate with tech giants and software developers to usher in an era of fully connected cars, promising unprecedented improvements in safety and a richer driver and passenger experience. To truly grasp the future of our automotive world, understanding the fundamentals of what constitutes a connected car is essential.

What Exactly is a Connected Car?

At its core, a connected car is a vehicle that has the ability to access the internet, thereby facilitating the seamless sharing of data with a multitude of devices, both within and beyond its physical confines. Presently, many vehicles can connect to the internet through dedicated smartphone applications. This connectivity allows for a range of convenient functions, such as remotely unlocking doors, locating a misplaced vehicle in a sprawling car park, and even pre-conditioning the cabin's temperature before you step inside. For passengers, particularly on longer journeys, cars equipped with 4G connectivity can act as mobile Wi-Fi hotspots, ensuring everyone stays online and entertained. The age-old lament of children asking, "Are we there yet?" may soon become a relic of the past, replaced by the quiet hum of digital engagement.

The Vision of Fully Connected Cars

The concept of fully connected cars represents a significant leap forward from the current market offerings. It envisions a world where vehicles are connected on a vastly more ambitious and comprehensive scale. The ultimate aspiration is to integrate as many elements of our environment as possible into a unified internet network, allowing them to communicate and interact seamlessly. Consider your smart home devices, your indispensable smartphones, and now, your car – all becoming integral components of a larger, interconnected ecosystem. In urban environments, such as bustling towns and cities, fully connected cars will possess the capability to converse with other vehicles on the road, as well as with pedestrians and the broader traffic infrastructure. This inter-vehicle communication, often referred to as 'talking,' will enable the real-time sharing of vital information. Imagine your car automatically rerouting to avoid congestion or accidents, or effortlessly locating available parking spaces, all without requiring extensive pre-planning from the driver. This is the promise of a truly connected automotive future.

The Pillars of Connected Car Functionality

For connected cars to deliver on their promise of an improved driving experience, they will primarily rely on three fundamental pillars: telematics, infotainment, and infrastructure. While this might sound like science fiction, it's important to recognise that the cars of today are already incorporating elements of these technologies to enhance our journeys. Let's break down each pillar:

Telematics: The Bridge to the Cloud

Telematics acts as the crucial link between the vehicle and 'the cloud.' This connection allows the car to gather and share a wealth of information concerning its performance metrics and the driver's behaviour patterns. The primary objective here is to leverage this data for continuous improvement in both the vehicle's operation and the driving style. This can range from optimising fuel efficiency to providing personalised driving feedback.

Infotainment: Enhancing the In-Car Experience

Infotainment systems are designed to provide vehicles with access to richer, more up-to-date information. This directly translates into enhanced navigation capabilities, more sophisticated display interfaces, improved audio quality, and a broader spectrum of in-car entertainment options. The result is a more engaging and enjoyable travel experience for everyone within the vehicle, whether they are behind the wheel or simply a passenger.

Infrastructure: The Foundation of Connectivity

Infrastructure stands out as the most critical element in establishing a truly interconnected network of vehicles. This encompasses what is broadly known as Vehicle-to-Everything (V2X) technology. V2X is an umbrella term that covers three key forms of wireless communication:

Vehicle-to-Vehicle (V2V)

V2V technology empowers connected cars to exchange information wirelessly with other vehicles in their vicinity. This could include data about speed, braking, and intended manoeuvres, allowing for proactive hazard avoidance and smoother traffic flow.

Vehicle-to-Pedestrian (V2P)

V2P technology enables connected cars to communicate with vulnerable road users, such as pedestrians and cyclists. This could involve alerting drivers to the presence of a pedestrian crossing the road or warning a cyclist of an approaching vehicle.

Vehicle-to-Infrastructure (V2I)

V2I technology facilitates the sharing and reception of information between connected cars and roadside infrastructure. This includes elements like traffic lights, road signs, sensors embedded in the road, and cameras. For instance, a car could receive real-time updates on traffic light timings to optimise its speed or be alerted to temporary road closures.

In all these V2X scenarios, communication is typically carried out using advanced cellular network technologies like 4G. The overarching goal is to significantly reduce the risk of collisions, bolster overall road safety, and contribute to a more pleasant and efficient journey for all road users.

The Crucial Role of 5G in V2X

While connected vehicles are already equipped to communicate using 4G, this technology, despite its advancements over older 3G networks, has inherent limitations. Specifically, 4G does not possess the ultra-high speeds and low latency required to power the complex, real-time data exchange necessary for a truly integrated V2X infrastructure. This is where the transformative potential of 5G comes into play. Promising speeds approximately ten times faster than 4G, the widespread deployment of 5G is expected to unlock a new era of technological innovation in the automotive sector. Predictions suggest that by 2025, a significant portion of the global vehicle fleet will be equipped with 5G connectivity, laying the groundwork for a revolution in how vehicles interact with their environment.

Why is Vehicle Connectivity So Important?

Beyond the immediate benefits of enhancing road safety and optimising traffic flow – which in turn can lead to reduced emissions – the longer-term vision for connected cars is inextricably linked to the realisation of autonomous and fully driverless vehicles. While the exact timeline for when driverless cars will become commonplace remains a subject of debate, with estimates varying widely, it is undeniable that V2X technology is a fundamental enabler of this future. The ultimate goal is a driving landscape where human intervention, such as steering and operating pedals, becomes largely unnecessary. Currently, many new vehicles feature Advanced Driver Assistance Systems (ADAS), which offer a degree of partial automation by providing warnings for hazards, traffic, adverse weather, and other potential dangers. However, the driver remains fully responsible for the vehicle's operation. As we progress towards full autonomy, these ADAS will evolve into even more sophisticated systems, becoming absolutely crucial for maintaining safety on the roads.

Addressing the Security Imperative

Any system that involves the wireless sharing of data inherently presents security challenges. Connected cars, by their very nature, share an immense volume of data with other vehicles and the surrounding infrastructure, powered by 4G and increasingly 5G networks. Much like our laptops and smartphones, connected cars are susceptible to cyberattacks and require robust protection measures. Recognising this critical need, the United Nations implemented regulations in 2020 aimed at safeguarding connected vehicles against cyber threats. These regulations are set to become mandatory for all new vehicles from July 2022. While cyber threats are constantly evolving, so too will the technological countermeasures designed to enhance the security of connected car systems.

When Will Connected Cars Be the Norm?

Pinpointing an exact date for when connected cars will become the 'new normal' is a complex task. Projections indicate that by 2023, a significant percentage of new vehicles will be equipped with V2V technology, and by 2024, over eleven million vehicles are expected to feature some form of V2X system. The advent of 5G broadband is undeniably accelerating our journey towards a fully connected network of autonomous vehicles. However, the implementation of such a sophisticated infrastructure is an immensely complex undertaking that will require years of development, standardisation, and regulatory alignment. Rather than a singular unveiling event, the transition to a fully connected automotive future will be a gradual, evolutionary process. With each new car model released and each software update deployed, an ever-evolving version of V2X will progressively become the accepted standard, seamlessly integrating into our daily lives.
