reckless driving

In the book fault in our stars Agusts is out side puts a cigarette in his mouth (but doesn't life it) then Hazel starts yelling at him then he tells her the metaphors of the "killing thing".  Then Hazel soon gets in August waters car then he starts driving but the only thing is that he is a weariness driver.   My thought is I think the instructors not have let him drive I'm scared for both of them.  My reaction was to the cigarette scene I would feel the same way but at least I would tell her first.
