I included relevant information to why I felt it "obvious": incentives (wages), training. That's the entire extent of what I feel relevant to discuss with regards to my wider argument. It's not my job or intent to defend how much increased safety it applies, or to save you from googling whatever supporting information you are actually looking for. I'm only arguing that Oregon given information they had at the time believed it to be in part a safety measure. Again, the correctness of that belief (especially at the time) is "obvious", and the actual "magnitude" of safety gained is irrelevant to any claim I am making and starts to move the debate out of context.
