Here in Victoria (Australia), we commonly see road signs stating that "speed kills" whereas the reality is that it is the jerk that kills.

No, it's the acceleration. That's what produces the forces. But there is usually a correlation between jerk and acceleration in a collision, given a certain amount of energy (speed^2)
