Insurance Institute for Highway Safety Finds Semi-Automated Driving Systems Inadequate in Ensuring Driver Focus

A recent testing by the Insurance Institute for Highway Safety (IIHS) has raised concerns about the effectiveness of semi-automated driving systems in ensuring that drivers remain focused on the road while using these features.

Insufficient Monitoring and Safety Alerts

According to IIHS President David Harkey, the testing revealed that the systems are not adequately monitoring the driver's attention and issuing alerts when necessary. This lack of vigilance and timely warnings poses significant safety risks for drivers and other road users.

Rating Results

Out of the 14 systems tested, none received the highest rating for their monitoring capabilities. Only the Lexus Teammate with Advanced Drive obtained an acceptable rating, while the General Motors Super Cruise and the Nissan ProPILOT Assist with Navi-link were rated as marginal.

Call for Improvement

The IIHS report emphasizes the urgent need for enhancements in monitoring, particularly the monitoring of the driver's head, eyes, and hands to ensure their readiness to take control of the vehicle when required. These improvements are essential for the safe and effective implementation of semi-automated driving systems.

Concerns and Regulatory Response

The growing concerns over the performance of driver assistance systems have prompted discussions among lawmakers. During a recent hearing before the Senate Committee on Commerce, Science and Transportation, National Transportation Safety Board Chair Jennifer Homendy and Democratic Sen. Ed Markey expressed reservations about the readiness and limitations of these systems in real-world driving conditions.

Automaker's Response

In response to the concerns raised, the Alliance for Automotive Innovation, a trade group representing automakers, emphasized that automated driving systems are designed to support human drivers, requiring continuous attentiveness and engagement from the driver. The trade group highlighted the positive role of features such as lane centering assistance technology and adaptive cruise control in reducing road crashes and injuries through automation and technology.
