I think some of this falls into the simulation paradox: the more accurate the simulation, the closer the simulation is to the thing being modelled. But it's a quadratic relationship in most cases, so at some point meaningful increases in simulation accuracy cease to be economically viable.



Yeah, but in the words of RyanF9, "The US government can afford a BB gun", so there's no reason that DOT can't test helmet visors.

The main reason the DOT standard is so bad is because its mired in bureaucracy and managed by a severely underfunded organization.
