Maybe he should resign. You know the good of the state and all that...
I agree that he should resign. He will clearly be unable to carry out the normal duties of his position. On top of that, he did this to himself, through irresponsible and illegal behavior. He chose not to fasten his seatbelt, and allowed (quite likely even encouraged) his state-employee driver to drive way, way over the speed limit, endangering the lives of other people on the road, as well as his own.
I think he will resign. He’s ridiculously wealthy. I think he’ll hire personal therapists and put all his energy toward recovery and getting back what he can of the rest of his life. That’s why I would do.
That sounds like a well thought out plan to me.
