The vehicle failed to properly respond to the closure, continued through and struck multiple traffic cones, and ultimately collided with the road-closure equipment, causing significant front-end damage. My primary safety concern is that multiple safety systems appeared to provide no effective intervention. I observed no Forward Collision Warning, no Automatic Emergency Braking, and no effective automatic braking or avoidance maneuver, even after the vehicle had already begun striking traffic cones.
