> "~5,500 person-years worth of driving between crashes"

That's between fatalities, not between crashes. The reported injury rate is 62 times higher than the fatality rate, and the overall police-reported crash rate is 170 times higher than the fatal crash rate.

You are correct, I missed the adjective on my second use. As my points were exclusively about fatal crashes and I never mentioned the injury or crash rate at any point and previously used 5,500 years exclusively in relation to fatal crashes, it should be obvious that I intended to mean that and my point still stands with that correction.

My primary concern is with your treatment of "unsafe" as meaning nothing less than "dead".
