if you want to push her away and make her resent you even more some of the play it hard advice you got here will work great, on the other hand I would suggest a more liberal approach due to her age, become her friend, work with her, if she wants to go out let her, drive her even, become her buddy, that way say she goes out gets drunk (that will happen) she will have no issues on calling you for help etc, a teenage girl is going to get into trouble no matter how hard nose you will act. its better to be a friend compared to the do as I demand parent, that only works to age 14 most of the time.
give her more freedom, let her do what she wants and be there for when she falls, sit down and talk about it, let her learn from the mistakes with no penalties from you.
