So I've been dealing with the topic for a long time. I think you have to assess the danger on the basis of the fatalitys that you can not influence yourself. When I'm risking driving a car, I increase my chances of dying just as if I jumped risky. If you look at the skydiving only the accidents that happen through material failure and you can not influence the accident rate would have to be almost 0 while, for example, when driving is still exposed to a higher risk by the many other road users.
