[Gone to the bowtie side]

Man, you are lucky to be alive.
I had a friend lose an argument with a brick wall in his minivan. He fell asleep and crashed. Unfortunately, he never woke back up from his initial unconsciousness and died two days later from having the steering wheel crush his sternum and other injuries.
I've learned the hard way to not skimp on sleep and then drive. I've done many a duty day with lack of sleep in the military then expected to drive home the next day. I would get a quick nap to fix me up. All it takes is a few seconds.
