Deputy kills 2, 1 in critical cond.

Not really, and not for all people. I've known people that can fall asleep in seconds, one friend in particular can drop off without warning. Yes, it's happened while we were in the car, I realized what had happened, woke him up and had him pull over so I could drive.

That brings up an interesting point... should someone who knows they can fall asleep in seconds without warning take extra special care not to drive when they are tired? It's like, if you have bad vision you know not to drive without your glasses. Why tempt fate and make a careless decision to drive when you haven't had enough rest?
