"Statistics"
Traffic lights are never sited at intersections without a statistical history of accidents. There are some who would argue that they "believe" an accident "could" happen but can't produce the evidence to say what the "probability" of an accident is.
Statistics provide this data.
Because a six pack of enthusiasts believe something "could" happen, the majority are then expected to go along with their theory and spend heaps of money that simply is not justified.
The justification comes with gathering the data to prove there is a better than good "probability" not just a possibility.
A near miss (or hit) in a CTZ or class G, like a VCA, is a failure of proceedure.
One addresses the cause, not the complaint when looking for a remedy.
