When someone involved in a high-risk sport suffers an accident and dies, others in that sport often talk about how the deceased failed to take adequate precautions. Why?

High risk sport is one in which involves high speeds and the chances of risk are very high.

Thus when the person involved in high risk sport dies, other participants of that sport focus more on the precautionary measures and the precautions which the deceased person failed to take so that the focus of the participants is more on the precautions for their survival while being in the sport and not on the deceased person.
