stevemfr, I respectfully disagree. I am all for people taking responsibility for their actions and suffering the consequences. I think that this is a different and dangerous situation. The fact that the car could go completely under the guardrail, as seen in this photo,

means to me that the design or placement of the rail dangerous and needs to be changed.
Of course we don't know what the situation was that lead to this accident, but normally a guardrail would have deflected the car back onto the road. Whether it would have struck something else and caused a fatality is speculation. What we do know is this guardrail didn't work because it is too high and that led an unnecessary fatality.
