ADAS use automated technology, such as sensors and cameras, to detect nearby obstacles or driver errors, and respond accordingly.

As most road crashes occur due to human error,[2] ADAS are developed to automate, adapt, and enhance vehicle technology for safety and better driving.

[3] Safety features are designed to avoid crashes and collisions by offering technologies that alert the driver to problems, implementing safeguards, and taking control of the vehicle if necessary.

Similarly, Lane Keeping Assistance is shown to offer a reduction potential of 19%, while Blind Zone Detection could decrease crash incidents by 9%.

[4] According to a 2021 research report from Canalys, approximately 33 percent of new vehicles sold in the United States, Europe, Japan, and China had ADAS.

[9] Modern cars have ADAS integrated into their electronics; manufacturers can add these new features during the design process or after production via over-the-air (OTA) updates.

ADAS are considered real-time systems since they react quickly to multiple inputs and prioritize the incoming information to prevent crashes.

[10] ADAS are categorized into different levels based on the amount of automation, and the scale provided by The Society of Automotive Engineers (SAE).

[58] According to a 2021 research report from Canalys, approximately 33 percent of new vehicles sold in the United States, Europe, Japan, and China had ADAS features.

[5] Major car brands with Level 2 features include Audi, BMW, Mercedes-Benz, Tesla, Volvo, Tata, Citroën, Ford, Hyundai, Kia, Mazda, Nissan, Peugeot, Mahindra and Subaru.

[59] On June 29, 2021, the National Highway Traffic Safety Administration (NHTSA), the branch of the United States Department of Transportation responsible for federal motor vehicle regulations, issued Standing General Order 2021-01 (SGO 2021-01),[60] which required manufacturers of ADAS (Levels 1 or 2) and Automated Driving Systems (ADS) (Levels 3 through 5) to promptly report crashes that occurred when driver-assistance or automation systems were in use.

[63] The data are subject to several caveats and limitations; for instance, manufacturers are not required to report the number of vehicles that have been built and equipped with ADS/ADAS, the number of vehicles operating with ADS/ADAS, or the total distance traveled with ADS/ADAS active, which would be helpful to normalize the incident report data.

[60] According to the initial data covering July 2021 to May 15, 2022, ADS (Levels 3–5) from 25 different manufacturers were involved in 130 crashes, led by Waymo LLC (62), Transdev Alternative Services (34), Cruise LLC (23), General Motors (16), and Argo AI (10); because multiple manufacturers can report the same crash, the sum exceeds the total number of reportable incidents.

[66] To help with standardization, SAE International has endorsed a series of recommendations for generic ADAS terminology for car manufacturers, that it created with Consumer Reports, the American Automobile Association, J.D.

[70] Auto insurance for ADAS has directly affected the global economy, and many questions have arisen within the general public.

[71] ADAS are expected to streamline the insurance industry and its economic efficiency with capable technology to fight off fraudulent human behavior.

In March 2014, the US Department of Transportation's National Highway Traffic Safety Administration (NHTSA) announced that it will require all new vehicles under 10,000 pounds (4,500 kg) to have rear view cameras by May 2018.

Cameron's father backed up his SUV over him, when he did not see the toddler in the family's driveway [73] The advancement of autonomous driving is accompanied by ethical concerns.

The earliest moral issue associated with autonomous driving can be dated back to as early as the age of the trolleys.

However, as the advancement in ADAS proceeds, the trolley problem becomes an issue that needs to be addressed by the programming of self-driving cars.

[75] This raises questions such as “whose lives should be prioritized in the event of an inevitable crash?” Or “What should be the universal principle for these ‘crash-algorithms’?” Many researchers have been working on ways to address the ethical concerns associated with ADAS.

This approach first necessitates a system established with the agreement of car manufacturers, transportation engineers, lawyers, and ethicists, and should be set transparently.

[82] These systems promote active safety by increasing the efficiency of roads, possibly by adding 22.5% capacity on average, not the actual count.
