The Hidden Dangers of “Safe” Driver Assist Tools

The Rise of Advanced Driver Assistance Systems (ADAS) and Concerns About Safety

Drivers across the US and globally are increasingly drawn to the idea of driving vehicles that can automatically change lanes and maintain speeds on highways, thanks to the introduction of advanced driver assistance systems (ADAS). Automakers argue that these systems offer both convenience and safety benefits, particularly on long trips where driver fatigue can set in, by reducing human error. However, a recent report by The Insurance Institute for Highway Safety (IIHS) raises doubts about the safety improvements brought by these technologies.

IIHS tested ADAS systems from 14 car manufacturers and found that none of them received the highest “good rating,” with 11 systems receiving a “poor” rating instead. This underscores the need for rigorous testing to ensure that the advertised safety features of ADAS are effective and not inadvertently causing more harm. The results highlight the critical role of independent safety evaluations in verifying the claims made by carmakers regarding the safety of their ADAS systems.

ADAS systems utilize onboard cameras and sensors to analyze road conditions, assist drivers in maintaining speeds, and apply brakes when necessary. Popular systems like Tesla’s Autopilot and Full-Self-Driving can also facilitate lane changes automatically. According to Counterpoint Research, ADAS-equipped vehicles accounted for 46% of new car sales in the US in the first half of 2022, indicating a growing trend towards adopting these technologies.

It is essential to distinguish ADAS systems from fully autonomous vehicles, as drivers using partial automated driving systems are legally obligated to remain vigilant and be prepared to take control of the vehicle at any moment. Despite some automakers’ misleading branding that might suggest otherwise, ADAS systems require active driver involvement and oversight.

The IIHS report specifically scrutinizes systems from various car manufacturers, highlighting deficiencies such as the failure to detect driver attentiveness or provide adequate reminders to keep drivers focused. Some systems even allow activation without the driver wearing a seat belt, raising concerns about accident prevention and driver safety. This underscores the need for continued evaluation and improvement of ADAS technologies to ensure their effectiveness in enhancing road safety.
