Vidal is a fucking imbecile. Then again he has struggled with drugs before and some say he suffers from alcoholism... you wonder what his wife was thinking getting into the car with him in that state.
He will lose his license and face jail time (which he will most likely avoid, as most do in most countries), but the coach is not going to punish him. He's incredibly lucky that no one else got hurt: if the collision had led to a serious injury chilean law stipulates he would have had to spend a minimum of one year in prison.
