Seems like yet another case of a flawed study or a flawed article based on a misunderstanding of the study.
Statements like the quote above make no sense as "withstanding a 5,000lb vehicle" makes no sense. A 5k lb vehicle traveling at 70MPH is carrying several orders of magnitude more energy than a 5k lb vehicle traveling at 5MPH. Likewise a direct, perpendicular hit will impart more energy than a glancing parallel blow, so what are they really rated for?
In any case, these guardrails are used in places where 100k lb semis are traveling at highway speeds, and there have never been any other doom and gloom articles written about that. I don't think we need to completely rebuild our highway system simply because heavier cars exist.
Maybe heavier cars and vehicles should have a lower speed limit then.
That could have an adverse effect. There are processes in place for this.
The transportation administration in your area determines speed limits using several factors. Before I moved, the city I was in adjusted speed limits for several roads over a year long period. They reduced crashes by raising the limit on a handful of roads. They needed less policing for enforcement and traffic flow improved. After the study was completed, it stayed. Another example is a road they lowered the speed limit on resulted in higher crashes. So they put it back to what it was originally. And interestingly, in a construction zone where they had to lower the speed limit for the crew, they found that the lower speed limit overall, even when the crew went home, resulted in reduced crashes. For that area they just decided to keep that limit after construction was complete.
Maybe we should make car accidents a felony crime punishable by up to 20 years in prison.
