The Six Levels of Autonomous Driving and the Challenges They Bring!
The Six Levels of Autonomous Driving and the Challenges They Bring!
Created with the help of DALL-E
Autonomous driving is rapidly evolving technology that promises to revolutionize the way we commute, work and travel. With the advancements in sensors, machine learning, and artificial intelligence, self-driving cars are becoming more common on roads across the world. However, the concept of autonomous driving can be complex, and it is important to understand the different levels of autonomy that exist in these vehicles. The Society of Automotive Engineers (SAE) has defined six levels of autonomous driving, ranging from no automation to full automation. In this article, we will explore each of these levels in detail and discuss what they mean for the future of transportation. Understanding the levels of autonomous driving is crucial for anyone interested in this technology, as it provides a framework for understanding its capabilities, limitations, and potential impact on society.
The Society of Automotive Engineers (SAE) has defined six levels of autonomous driving, ranging from no automation (Level 0) to full automation (Level 5):

The driver is in complete control of the vehicle at all times.
- Standard Vehicles without any driver assistance features.
- Require the driver to control all aspects of the vehicle, such as steering, braking, and acceleration, but the vehicle might have some warning lights or sounds.

The vehicle can assist the driver with certain functions, but the driver remains in control.
- Vehicles with basic driver assistance features that can assist the driver in certain situations.
- Adaptive cruise control, lane departure warning, and automatic emergency braking systems.
Examples:
2020 BMW Series 3, 2020 Volvo S60

The vehicle can take over some driving functions, but the driver
must remain alert and ready to take control at any time.
- Vehicles with advanced driver assistance features that can take over some driving functions, such as: acceleration, braking, and steering.
Examples:
Tesla’s Autopilot system*, Audi’s Traffic Jam Assist, and Cadillac’s Super Cruise.
*Tesla has some level 3 or even 4 functionality, but without official certification, and it keeps updating.

The vehicle can handle most driving functions in certain conditions, such as on a highway, but the driver must be ready to take over when the system requests it.
- Vehicles with advanced autonomous driving features
Examples:
Honda Legend sedan, Audi’s AI Traffic Jam Pilot, Mercedes-Benz’s Drive Pilot, and BMW’s iNEXT.

The vehicle can handle all driving functions in certain conditions and environments, without the need for a human driver to take over within a geofence.
Examples:
Waymo’s, google fully autonomous cars, Baidu’s Apollo vehicles and GM’s Cruise AV.

The vehicle can handle all driving functions in all conditions and environments, without the need for a human driver to take over at any point.
Examples:
There are currently no commercially available cars that meet this level of automation. However, some companies are working towards achieving this goal, such as Tesla, Waymo, and Cruise.
Key hardware to enable autonomous driving
Self-driving cars rely on a variety of hardware (HW) components to enable their autonomous capabilities. Some of the key hardware components used in self-driving cars include:
- Sensors: Self-driving cars use an array of sensors to perceive their environment, including radar, lidar, cameras, and ultrasonic sensors. These sensors provide the car with a detailed view of its surroundings, including the position and movement of other vehicles, pedestrians, and obstacles.
- GPS: Global Positioning System (GPS) is used to determine the car’s location and provide it with navigation information.
- Drive-by-wire (DBW): Self-driving cars rely on sophisticated control systems to manage their acceleration, braking, and steering. These systems use electronic signals instead of mechanical connections to provide more precise control and safety features than traditional mechanical systems and also to make it possible for ADAS systems to control the car.
- High-performance computing systems: Self-driving cars use powerful computing systems to process the large amounts of data generated by their sensors and other inputs. These systems use artificial intelligence and machine learning algorithms to make decisions about how to drive the car.
- Communication systems: Self-driving cars need to communicate with other vehicles and infrastructure in their environment to ensure safe and efficient operation. This requires sophisticated communication systems, including vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication protocols.
Overall, the hardware components used in self-driving cars are complex and require significant engineering expertise to design and integrate into a working system.
Legal obstacles
Self-driving cars present several legal obstacles that need to be addressed before they can become widely adopted. Some of the key legal obstacles include:
- Regulatory framework: The legal framework for self-driving cars varies from country to country. Regulators need to develop comprehensive and consistent regulations that cover everything from safety standards to liability issues.
- Liability: One of the biggest legal obstacles facing self-driving cars is determining who is responsible in the event of an accident. determining liability can be challenging because of the multiple parties involved in the development and the operation, and how would the car act under if it’s faced with a moral decision like the famous trolly problem.
- Data privacy: Self-driving cars collect vast amounts of data about their passengers, their environment, and their operation. Regulators need to establish clear guidelines for how data is collected, used, and shared to protect privacy and prevent misuse.
- Cybersecurity: Self-driving cars are vulnerable to cyber-attacks, . Regulators need to establish standards for cybersecurity to prevent unauthorized access to self-driving cars and ensure that they are protected against malicious attacks. WHAT IF it’s used to assassinate people !
- Public acceptance: Finally, self-driving cars need to gain public acceptance before they can become widely adopted.

Cities build for self-driving cars
It’s much easier to build a city for self-driving cars than building them to operate in our current cities, with it’s complex setup and driving situations.
Here are some of the features that could be included in a city built for self-driving cars:
- Dedicated lanes and roads:
These lanes could be equipped with sensors, communication systems, and other technologies that would allow self-driving cars to operate safely and efficiently. - **Smart traffic management:
**That would optimize traffic flow and reduce congestion. This system could use real-time data from sensors and other sources to adjust traffic signals, reroute traffic and make use of V2V communication. - Electric charging infrastructure:
**It could have a comprehensive electric charging infrastructure to support the widespread adoption of electric vehicles or even a road which charge the cars wirelessly while in motion this concept is called **dynamic charging . - **Integrated public transportation:
**Using autonomous vehicles to provide seamless transportation options for residents. This could include on-demand shuttle services that could take passengers to and from public transportation hubs.
Overall, this future is coming sooner or later, I hope the article gave you some insights, Feel free to leave comments and don’t forget to follow me for future articles, thank you for your time :)
