In another apparent case of regulation and oversight not doing what they’re supposed to do, highway guardrails have come under scrutiny.
Part of the problem is this (it’s a problem inherent in large systems that cannot be avoided; which is why large systems should be avoided): many people in the regulatory agency decide to sign off on the use of these guardrails. Billions of dollars are spent. Then, a problem arises. Do those people, does the agency, want to admit it was wrong? No. Even if it wanted to admit it was wrong, does the agency have the financial capacity to correct or reverse the decision? Probably not. The problem is that large systems cannot correct bad behavior, assuming they even want to (which often they don’t).
