Most Autonomous Driving Systems Fall Short on Ensuring Driver Attention, IIHS Study Finds

Most automated driving systems don't ensure drivers are paying attention or issue strong warnings, per an IIHS study. Only 1 of 14 got an "acceptable" rating.

The IIHS introduced the ratings to get automakers to follow standards on monitoring drivers and issuing warnings.

The Lexus Teammate system was the only one rated "adequate" for driver monitoring features.

No system met all of the institute's driver monitoring requirements, but Ford's came the closest.

Automakers say they are already making changes and updates in response to the IIHS ratings and feedback.
