FYI: While autonomous driving technology promises a safer future, current Advanced Driver Assistance Systems (ADAS) are proving to be effective now and need broader implementation.
The Safety Potential of ADAS vs. Self-Driving Technology
Self-driving technology is often heralded as the ultimate solution to road safety, yet the evidence supporting its effectiveness remains sparse. In contrast, Advanced Driver Assistance Systems (ADAS) with crash avoidance features are already delivering tangible results and should be more widely integrated into today’s vehicles.
The Rising Threat of Road Accidents
Road accidents remain a major public health issue in the United States. According to the National Highway Traffic Safety Administration (NHTSA), nearly 41,000 people lost their lives in motor vehicle accidents in 2023. This marks a troubling increase over recent years.
Billion-Dollar Investments in Autonomous Cars
To address this escalating crisis, automakers are investing billions of dollars into developing self-driving technologies. The ideal future envisions a world where computer algorithms, supported by cameras, radars, and sensors, will take over the driving responsibilities from humans.
Proven Efficacy of ADAS Features
Experts argue that the key to safer roads may lie not in waiting for perfect autonomous driving systems but in the widespread adoption of ADAS technologies. David Kidd, senior research scientist at the Insurance Institute of Highway Safety (IIHS), emphasizes that these systems are already making a difference.
"Crash avoidance technologies are preventing crashes and are becoming more available on new vehicles," Kidd noted.
ADAS: A Strong Safety Net
Modern vehicles are increasingly equipped with ADAS features such as forward collision alerts, autonomous emergency braking (AEB), lane-keeping assistance, and blind spot monitoring. According to the IIHS, these systems significantly reduce the types of crashes they are designed to prevent.
One prime example is AEB. This system uses radar and cameras to monitor the road ahead. When it detects an impending collision, it first checks if the driver is reacting by braking or steering. If no action is taken, the system automatically applies the brakes to slow down or stop the vehicle. The IIHS stated that AEB alone has reduced police-reported rear-end crashes by 50%.
The Uncertain Future of Self-Driving Tech
Conversely, semi-autonomous systems like Tesla’s Full-Self Driving, Ford’s Blue Cruise, and General Motors’ Super Cruise, which allow vehicles to drive semi-autonomously under certain conditions, do not show the same level of consistent safety improvement. There is also a concern that driver distraction might increase as people become more comfortable with these systems.
"Automation changes how people interact with the car. People may become more comfortable over time using it and they engage in more distracting activities," Kidd stated.
Data on Autonomous Systems: A Mixed Bag
The NHTSA has yet to directly link self-driving systems with increased distracted driving. However, the agency is vigilant and actively investigates potential safety defects in ADAS and autonomous driving systems.
Several studies offer conflicting views on the efficacy of self-driving tech. For instance, a study published in the journal Nature found that self-driving cars had a lower accident rate than human-driven vehicles, except during dawn, dusk, or turning scenarios. Meanwhile, an analysis of an NHTSA database showed an increase in accidents involving Level 2 semi-autonomous systems.
Looking Ahead: Regulation and Driver Education
Regulations are beginning to catch up. The NHTSA announced in April 2023 that by 2029, AEB systems must be standard on all new passenger cars and light trucks, capable of detecting pedestrians even in poor lighting conditions.
“We don’t think that should be allowed, especially knowing that it makes driving safer,” Kidd said, regarding the deactivation of crash avoidance systems like lane departure warning. He added that driver education would play a crucial role in maximizing the benefits of semi-autonomous and autonomous technologies, much like how drivers learn to adapt to electric vehicles.
Conclusion
Although autonomous driving technology holds promising prospects for the future, today’s focus should be on the broader implementation and optimization of ADAS features. Automakers and regulators should shift their efforts to ensure these proven systems are standard in all vehicles, paving the way for a safer driving environment now rather than waiting for a fully autonomous future.
