With the increasing acceptance of technology in all aspects of our lives, autonomous vehicles will undoubtedly transform the transportation industry in the next years. As a result, automakers are developing new business models and extensively testing autonomous vehicle models to meet customer demand for high-end, energy-efficient automobiles. But when will self-driving cars become commonplace?
The automobile industry is speeding towards a new future, driven by sustainability and electrification, as customer tastes alter and the demand to reduce emissions grows. Technology is infiltrating the automobile industry in such a manner that manufacturers are fast changing their business models and collaborating with partners to improve vehicle autonomy.
Many semi-autonomous driving systems, such as lane assist, adaptive cruise control (ACC), electronic stability control (ESC), rear-view video systems (RVS), adaptive highlights, forward collision mitigation (FCM), automatic emergency braking (AEB), automatic crash notification (ACN), and others, are already on the road.
Fully autonomous cars, on the other hand, are not far off. Waymo, a subsidiary of Google, has already driven its self-driving cars over 10 million miles in challenging conditions, while Tesla and Uber have also tested their driverless cars in order to approach autonomous vehicles in a staged way.
The degree of automation, according to the Society of Automotive Engineers, ranges from Level 0 (manual driving) to Level 5 (no driver interaction), and the auto industry is moving closer to fully autonomous vehicles as numerous businesses attempt to improve the technology.

The Automated System’s Five Levels
Level 0 Autonomous Vehicle (No Driving Assistance)
The driver is responsible for real-time duties like steering, accelerating, parking, and others in automobiles with zero level automation, however, there are certain automated devices in place to aid the driver. During driving, technological support systems may momentarily interfere to provide warnings or take action in particular circumstances.
The majority of automobiles on the road today are classified as Level 0.
Level 1 Autonomous Vehicle (Driver Assistance)
The latest automobile models have automatic driving assistance technologies that help to safeguard the car’s and driver’s overall safety. However, when it comes to operating the vehicle’s vital driving features, the driver retains a strong grip on the wheel.
Level 1 Automation automobiles include features like Adaptive Cruise Control, which maintains a safe distance between the vehicle and the traffic ahead of it without the need for user intervention. In general, at least one sophisticated driver-assisted feature is included in Autonomous Vehicle Level 1.
Level 2 Autonomous Vehicle (Partial Driving Automation)
In specified instances, Level 2 driving automation aids major driving functions such as steering, acceleration, and braking, but the driver must stay attentive and actively monitor the system at all times.
Level 2 driving automation technology includes the Highway Driving Assist function used in Kia, Hyundai, and Genesis automobiles, as well as Ford’s BlueCruise hands-free option. Tesla’s new Full Self Driving Capability technology is an Autonomous Level 2 system, and it will stay such until the over-the-air software upgrade adds the Autosteer capability for city streets.
Furthermore, by 2025, piloted auto functions in Level 2 and Level 2+ automation are predicted to increase at an exponential rate.
Level 3 Autonomous Vehicle (Conditional Driving Automation)
Under some situations, cars with Level 3 Automation can drive themselves, but not over long distances or on highways. The driver does not need to place his hands on the steering wheel at Level 3, but he must be prepared to regain control if the circumstances alter.
Level 3 automation makes judgments based on changing circumstances around the vehicle, such as fleet volume, weather conditions, and traffic congestion ahead, using different driver support systems and AI technology.
Audi claimed to be the first carmaker to create a vehicle with level-3 capabilities when it launched the A8 luxury sedan with LiDAR (Light Detection and Ranging) technology in 2017. Despite the promises, the Audi A8’s freshly designed system never got the regulatory certification, and the technical wonder is currently classed as a Level 2 car in the United States.
Honda, on the other hand, debuted its Legend premium car in early 2021 with an authorized traffic congestion help technology, which is now available for purchase in Japan. The revised Mercedes-Benz S-class and the 2022 Mercedes-Benz EQS electric vehicle with Drive Pilot technology are among the automobiles awaiting regulatory certification.
No Level 3 systems are currently allowed to use on American highways.
Level 4 Autonomous Vehicle (High Driving Automation)
Due to their self-driving mode, cars with Level 4 automation do not need human involvement in most situations. In Autonomous Level-4 driving, sophisticated driver support technologies may intervene if anything goes wrong. Drivers may override the self-drive mode and control the vehicle independently.
Level 4 automation vehicles can only operate in certain regions and at certain speeds due to legal and infrastructural constraints. Currently, Level 4 driverless technology is employed in public transportation vehicles such as robotaxis, which are programmed to move between points A and B and are limited by geofencing technology.
Severe weather may sometimes prevent or restrict the usage of Level 4 autonomous vehicles. In the United States, NAVYA, a French business, is creating and marketing Level 4 shuttles and taxis that can go up to 55 mph, while Magna, a Canadian automotive supplier, provides Level 4 capabilities in both urban and highway situations.
Volvo and Baidu recently formed a strategic alliance to build Level 4 electric cars for the Chinese robotaxi sector.
Level 5 Autonomous Vehicle (Full Driving Automation)
Because the vehicle will be allocated to undertake the “dynamic driving job,” level-5 or completely autonomous cars will need no human interaction.
These automobiles would be unrestricted by geofencing, allowing them to travel anywhere and accomplish whatever that a skilled driver could. Even if the weather was severe, the automobiles would remain unaffected. Furthermore, the fully automatic automobile would only need human intervention to specify a location.
Despite the fact that completely autonomous cars are being tested in many locations across the globe, commercial manufacturing is still a few years away.
Can Autonomous Vehicles Help to Solve Congestion in Cities?
Reduced traffic is one of the many advantages that autonomous cars may give to current road infrastructure. According to research done by the University of Cambridge, a fleet of self-driving cars working together to keep traffic flowing smoothly may reduce congestion in metropolitan areas by at least 35%.
Reduced traffic congestion and the number of cars on the road may result in fewer incidents of road violence and less pollution. Many times, the primary cause of traffic congestion is human participation, such as when a motorist refuses to let other vehicles change lanes, prevents cars from merging on highways, engages in unsafe driving practices, and so on.
Autonomous cars, on the other hand, prohibit drivers from engaging in conspicuous undesirable behaviors like blocking crosswalks and allow for a cooperative interaction framework to lessen visual congestion.
Vehicle-to-Vehicle Communication (V2V) enables autonomous cars to interact with one another by broadcasting and receiving data such as road conditions, traffic flow, speed, and direction. If another vehicle drifts into its lane, the sensors begin to generate a warning alert in the event of a prospective accident.
According to the United States Department of Transportation, vehicle-to-vehicle communication may lower the severity of non-impaired accidents by up to 80%, preventing hundreds of thousands of collisions each year.
Another important component of autonomous cars is platooning, which helps to keep traffic flowing and alleviate congestion by reducing aerodynamic drag and lowering fuel consumption and emissions.
Furthermore, the Adaptive Cruise Control technology may assist in automatically adjusting vehicle speeds based on the speed of other cars in the vicinity, allowing traffic to flow.
Are Self-Driving Cars a Solution to Climate Change?
Self-driving vehicles have significant environmental advantages, such as decreased carbon emissions, which may help to make the world a better place. Autonomous cars have the potential to lower oil usage by 2-4 percent by 2025, according to the Intelligent Transportation Society of America.
At least in suburban and high-income metropolitan areas, robotaxis and shuttle mobility have the potential to satisfy everyday mobility needs and put an end to bulk private-car ownership. Many businesses have already begun to test big fleets of shared autonomous cars.
In the next years, more convenience, improved availability, and the supply of economical mobility are projected to promote the deployment of robotaxis.
By 2030, the use of robotaxis and shuttles might result in a 20% decrease in the use of private automobiles. Robotaxis are designed to maintain a steady driving speed and a safe spacing between cars, reducing the need for unnecessary stopping and re-acceleration and lowering emissions.
Furthermore, sophisticated driving systems such as eco-navigation, wireless communications, adaptive cruise control, and other technologies might help to minimize pollution by reducing vehicle emissions.
While Google’s Waymo began giving driverless robotaxi rides in 2020, Alibaba-backed AutoX has unveiled Gen5, a completely autonomous robotaxis designed to successfully negotiate China’s difficult urban driving circumstances.
Why haven’t self-driving cars been mainstream yet?
Multiple testing operations have been taken out since the emergence of autonomous cars, and billions of dollars have been spent on fickle technology, but autonomous vehicles have yet to equal the skill of human drivers.
Furthermore, legislative struggles, environmental reasons, and safety concerns are preventing manufacturers from bringing autonomous cars to the road sooner. However, pervasive, reliable, quicker, and higher-bandwidth communication technologies may improve the capabilities of the autonomous vehicle network.
Engineers might use the cloud system to offload a lot of data processing from the cars, which would improve connection. Furthermore, creating smart cities with optimal traffic patterns may assist in removing the infrastructure barrier for autonomous cars, making driving more efficient and safer.
Other technologies for advanced driver assistance systems may make it easier for customers to adopt and use them over time.
