And presumably the non-accident death rate below 30 is even lower (relative to the population average).
Basically if an under 30 dies it's becoming more and more likely that it's a result of accident rather than anything else. And this causes people to become more and more cautious. i.e. it used to be that people had a real chance of death anyway, so taking a (physical) risk is not that big an increase in risk, but now it's a larger relative risk.
