In the case of an unavoidable suicide, it gets mitigated up to a point where any course of action is pointless because it would not serve road safety. The outcome would be the same. The difference here is that even if the pedestrian or cyclist was in the wrong, you're not automatically in the right. Your own behaviour as a motorist stands on itself, and you're supposed to take the difference in size and weight into account. Although it may not appeal to everyone's sense of fairness and just punishment(although, in fairness, only one of the parties can realistically be mauled or even killed), but from a road safety perspective it leads to more careful driving.
