Wish I had a great answer for that question as well .... and send my heartfelt sorrow at the loss of such promising lives ....

Now, I'm going to get a bit practical ... sometimes the very reason that the drunk driver comes out so much better off in bad accidents has to do with their slowed reflexes .... they don't react as quickly (which gets them into the accident) and so their body doesn't get all tense, etc. so when their body hits the "immovable object" they sustain much less bodily damage.....doesn't answer why the other person(s) had to die .... but does answer why the drunk driver survives in better shape so often.
