Nah, a car crash is too easy. I think this was meant to illustrate the fact that he lacks discipline and can't even act on his decisions. It will come back to haunt him, but I guess he doesn't care much since he's gonna die, anyway.
And as I thought and said a few chapters ago, he's living in a single timeline. I wonder whether he's gonna meet people he previously met in other bodies. Things are gonna get messy.
