Summary
Biondi, Goethe, Cooper, and Strayer examined how naive drivers interact with a Level-2 vehicle on real highway roads. Participants drove a 2016 Honda Accord equipped with Honda Sensing (Adaptive Cruise Control and Lane Keeping Assist) for approximately one hour while subjective trust, acceptance, and stress ratings were collected. Drivers rated the Level-2 features as a potential source of stress, particularly under denser traffic, and judged ACC more usable than LKAS; perceived stress with LKAS increased over the drive as drivers monitored its limited and inconsistent functioning.
Key finding
On-road exposure to Level-2 automation produced rising stress ratings (especially for Lane Keeping Assist) and a preference for traffic-free conditions, suggesting Level-2 HMI design needs to better support continuous supervisory monitoring.
Methodology
On-road exploratory study of one-hour highway drives in a 2016 Honda Accord with ACC and LKAS engaged, with subjective trust/acceptance/stress ratings and qualitative comments collected.
