Not necessarily.  Some accidents are simply not avoidable.  And some people are just naturally not as skilled as others.  That is a risk I take into account every time I get on the road.  (The road built with my tax dollars, by they way.)

That in no way makes it acceptable for some people to put other peoples lives at risk against their will simply because they feel like being irresponsible.  People who do so should be punished for being irresponsible idiots and unnecessarily endangering others against their will for that indiscretion alone.  If they roll the dice and end up killing someone, they should be punished for both opting to roll the dice and for the death (or injury) resulting from their decision.  My society agrees with me.
