This Guardrail Spun a Car Back Onto the Road

This guardrail just spun a car back onto the road. On a sharp curve, a concrete wall stops a car hard: the front crumples, and the car can bounce back into traffic. A roller barrier puts a yellow foam roller on every post. When a car hits, the rollers turn instead of pushing back, so the push becomes spin and the car rolls along the curve and back into its lane, like a bowling ball on the bumpers. This 3D animation is a simplified simulation for illustration, not a crash test. #Shorts #RoadSafety #Engineering
