Taking risks is not the same as cheating death.
Driving a motorcycle is not something you do to get an adrenaline high, yet from a strictly transportation perspective, it's a bigger risk than driving a car.
I think it has to do with priorities. Death is not the worst that can happen to me, hence I don't chose the safest option in every decision, because even though a long life is desirable, it's not the most important thing.
The sense of freedom is often worth more than the safest option.
