Alas, but the body count usually must be worryingly high before the "hmm, well, maybe we should do something?" thing kicks into gear. Daylight unescorted bomber raids, for example, or a space shuttle departing itself most awkwardly, usually after the attrit rate is already out the barn door and up and over the third ridge is action taken. Fixes may also require a change of thinking, which may be awkward for some, especially where reputations are involved, or piles of Mammon so high that a Jesus himself would throw his back trying to turn those tables at Wall-street. The engineering on the space shuttle was near perfect, right? And then you need ongoing vigilance soas to help slow down the rate of repeats where, spoilers, o-rings were again involved in the almost-disaster that was the Starliner. Squick-worthy adtech? Meh, hasn't gotten enough killed. Yet.
