Unfortunately the forces of natural selection are somewhat split in their usefulness. For every "just as well you stupid jerk" you usually lose at least one "so I was just walking along and this idiot driving with their phone in their hand..."
Natural selection also only works if you assume the dangerous behavior in question is entirely tied to genes and if the person engaging in the behavior dies before reproducing.
But yeah casual jokes about social Darwinism ftw!
