I rarely think about how guardrails are beneficial as to either prevent or reduce the degree of impact during collision. Having seen on the media every so often, I generally remember a deadly scene if the accident is associated with guardrails, as like as a reminder. Thanks to the advanced simulation technology, we can predict consequences of the change in the height of the guardrail in advance: Slightly Taller Guardrails Could Save Your Life
