In this guide, we discuss everything you need to know about self-driving cars and car insurance, including the cost, types of cover, and more.

Key points

  • Self-driving cars, also known as autonomous vehicles, operate without human input using technologies like sensors, cameras, AI, and machine learning to safely navigate roads

  • Autonomous driving technology is categorised into six levels, from 0 (no automation) to 5 (full automation), with varying degrees of human intervention required

  • Insurance for self-driving cars is evolving, focusing on the reliability of AI systems and facing challenges in determining liability, with experimental models being tested to address these issues

What is a self-driving car?

A self-driving car, also known as an autonomous vehicle, operates independently of human input. These vehicles are equipped with advanced systems for environmental perception and decision-making.

The development of self-driving cars started in the mid-20th century and has evolved significantly since then. Today, they incorporate a mix of technologies such as sensors, cameras, artificial intelligence, and machine learning.

These technologies enable the vehicles to navigate roads safely. They help in understanding traffic conditions, detecting obstacles, and managing driving tasks like steering, braking, and accelerating.

How do self-driving cars work?

Self-driving cars have installed sensors and cameras that continuously scan the environment as they collect data from road signs, traffic signals, obstacles, and other vehicles.

This data is processed by sophisticated software and algorithms. These systems interpret the sensory information to understand the surroundings. They make decisions and navigate roads safely. The software calculates the car's speed and the distance to obstacles, adjusting the path as needed.

At the core of self-driving cars is artificial intelligence (AI). AI enables these vehicles to learn from vast datasets and improve over time. It mimics human cognitive functions. AI allows self-driving cars to make complex decisions in real-time. These include identifying pedestrians, predicting other drivers' actions, and choosing the safest route.

What are the levels of autonomous driving in driverless cars?

Autonomous driving technology is divided into six levels, from 0 to 5. Each level indicates the car's ability to drive itself without human input

  1. Level 0 - no automation: The driver fully controls the vehicle. Automation includes basic functions like emergency braking or electronic stability control

  2. Level 1 - driver assistance: Features include cruise control and steering assistance. The driver controls most functions and must always be ready to intervene

  3. Level 2 - partial automation: The vehicle manages steering and acceleration/deceleration. The driver must keep their hands on the wheel and remain alert

  4. Level 3 - conditional automation: The vehicle handles all safety-critical functions in certain conditions. However, the driver must be ready to take over when needed

  5. Level 4 - high automation: Cars operate independently in most conditions without driver input. Human intervention may be needed in extreme scenarios

  6. Level 5 - full automation: This is the peak of driverless technology. These vehicles require no human interaction and manage all driving tasks

Each level's current legal status in the UK varies. Fully autonomous vehicles (levels 4 and 5) are still under trials and regulatory review. Levels 0 to 3 are already on the roads, with specific regulations ensuring safety and compliance.

How will self-driving car insurance work?

Introduction to autonomous vehicle insurance

As autonomous vehicles become more mainstream, car insurance policies must evolve. Traditional car insurance relies on the driver's history and behaviours. However, with self-driving cars, the focus shifts significantly. Insurers may need to consider the AI systems' reliability and decision-making algorithms.

Challenges in autonomous vehicle insurance

One major challenge is determining liability in accidents involving self-driving cars. Pinpointing fault — whether it's the manufacturer, software provider, or human occupant is complex. This requires a rethinking of liability frameworks and possibly new insurance models.

Experimental insurance models

Various experimental insurance models are being tested to address these issues. These models include usage-based insurance that considers vehicle autonomy levels.

They also include hybrid models that account for both technology's role and any human intervention. As these models are refined, they will likely set precedents for future autonomous vehicle insurance structures.

How much will it cost to insure a self-driving car?

When considering car insurance premiums for self-driving cars, several factors come into play that could influence premiums. Here's a breakdown of what might affect the cost of insuring an autonomous vehicle:

  • Impact of technology on insurance premiums: Advanced technologies in self-driving cars, such as sensors and software that enable autonomous driving, might initially increase insurance costs. These technologies are expensive to repair or replace if damaged. However, as these technologies become more common and repair costs decrease, insurance premiums could potentially lower

  • Comparison of costs with traditional vehicles: Currently, insurance for traditional vehicles is based on factors like the driver's history, the car's make and model, and the likelihood of theft. For self-driving cars, the focus may shift more towards the risk of technological failure rather than human error. This shift could result in different pricing structures compared to conventional vehicles

  • Future predictions for insurance pricing: As self-driving technology proves its reliability and safety records improve, insurers might reduce premiums. The rationale is that better safety features and reduced human error could lead to fewer accidents and claims. However, the overall impact on insurance costs will depend on how quickly this technology evolves and is adopted by the public

Are self-driving cars safe?

Yes, statistically, self-driving cars often have fewer accidents per mile than human-driven vehicles, making them appear safer on paper. This is because they adhere strictly to road rules and react without human reflex delays.

However, they are not without faults. Notable incidents have raised concerns about their handling of unpredictable scenarios, which human drivers might navigate more successfully.

Safety features in autonomous cars are rapidly advancing. These vehicles are now equipped with advanced sensors and algorithms. These improvements aim to enhance decision-making and reduce accident likelihood, potentially making self-driving cars safer as technology advances.
