With the proliferation of advanced driver assistance systems (ADAS) across vehicle brands, driver monitoring has become increasingly important. However, the Insurance Institute for Highway Safety (IIHS) has found that, among more than a dozen automakers, only Lexus’ system adequately performs.
The IIHS conducted evaluations on 14 driver monitoring systems from nine automakers and determined that only Lexus’ Teammate system, tested in the Lexus LS, deserved an Acceptable rating. Two systems were deemed Marginal, while the remainder received Poor ratings.
David Harkey, the president of IIHS, highlighted the testing of systems from various manufacturers, including BMW, Ford, GM, Genesis, Lexus, Mercedes-Benz, Nissan, Tesla, and Volvo. He expressed concern that most systems lack effective measures to prevent misuse and keep the driver focused on the road.
Several systems failed to appropriately warn or detect distracted drivers, with some even allowing the driver to remove their seatbelt while using ADAS. In instances where drivers neglect warnings, IIHS suggests emergency protocols that include a 35-second response window followed by a forced slow down, alert to emergency services, and disabling of ADAS to prevent crashes.
Harkey also emphasized the importance of driver involvement even with ADAS engaged. He cautioned against systems that independently make lane changes or that discourage driver steering inputs for fear of deactivating the system.
Despite the appeal of ADAS for long drives, Harkey points out that they may introduce new risks without proper safeguards, as some high-profile crashes have shown.
Lexus’ Teammate system stands out not just by its moniker but also by its balanced performance. Although not perfect in every respect, it has shown none of the significant weaknesses some other systems demonstrate. Harkey offers an optimistic view that the issues with these systems could be resolved through software updates.

FAQ Section
- What is a driver monitoring system?
- A driver monitoring system is a feature in vehicles equipped with advanced driver assistance systems (ADAS) that tracks the driver’s attention and engagement to ensure they are not distracted or incapacitated while the ADAS is operational.
- How did the IIHS rate the different driver monitoring systems?
- The IIHS rated Lexus’ Teammate system as Acceptable, two systems as Marginal, and the remaining 11 systems as Poor out of 14 systems tested from nine manufacturers.
- Why is the Lexus’ Teammate system rated higher by the IIHS?
- The Teammate system by Lexus received a higher rating because, according to IIHS, it performs better than others in monitoring the driver’s attention and engagement, ensuring that they are focused on the road when the ADAS is in use.
- Can software updates improve the performance of driver monitoring systems?
- According to IIHS President David Harkey, many of the shortcomings in current driver monitoring systems could potentially be fixed through software updates.
Conclusion
The IIHS has spotlighted the efficacy of driver monitoring systems, particularly singling out Lexus’ Teammate system as a model that successfully keeps drivers engaged. This assessment underscores the importance of such systems in the burgeoning field of semi-autonomous driving. Automakers are encouraged to heed the IIHS’ findings and improve their systems, likely through updates and enhancements. Ultimately, this technology serves as a critical component in ensuring the safety and reliability of ADAS-equipped vehicles on the road.
