This study assessed a driver’s ability to safely manage Super Cruise lane changes, both driver initiated (Lane Change on Demand, LCoD) and system triggered Automatic Lane Changes (ALC); these features allow drivers to command highway-based lane changes, as well as enable the system to automatically initiate and manage lane changes. The study was performed under naturalistic conditions on public roads in the Washington, D.C. area with 12 drivers each of whom were provided with a Super Cruise equipped study vehicle over an approximately 1-week exposure period. Drivers were shown how to operate Super Cruise (e.g., system displays, how to activate and disengage, etc.) and provided opportunities to initiate and experience commanded lane changes (LCoD), including how to override the system.
