Turning in water is a lot harder than turning a wheeled vehicle on land. Cars can turn themselves in a tight radius, container vessels cannot.
I also don't think the weight of the guardrail is what matters. Its strength is derived from the strength of the materials and being anchored in the earth.
In any case, any vehicle driving directly into a guardrail is going to plow right through.
I just don't think this guardrail thing is a great analogy.
- lelandbatey 3y agoThey're a pretty good analogy because you use a deflector style guard in the bay that ALSO is anchored in the earth. Nobody stops a whole cargo ship traveling straight at a thing via brute stopping power. You don't do it with cars and you don't do it with boats. You use deflectors that are roughly parallel to the direction of travel. Otherwise, all you can do is build a giant bunker which is not cost effective.
