The guy had been awake all night and fell asleep while driving. That was his choice.
How many of us who work on call end up with no sleep and the have to go into the office the next day. Employers are expecting staff to turn up and also to cover out of hours. Sure there will be some who have a responsible approach, but many don't. Couple this with the macho act from many who do provide in call cover and I wonder how long it will be before some systems admin who has been up all night fixing a problem or who has spent 20 hours in the office kills someone or themselves while driving home.
"The bastard" is an easy target and has served the sentence set down by the law. How do we address someone who ends up doing the same because they are overtired because of their work? A good reason for having the Working Time Directive.
