Do you want it to be _painful_, or do you want it to be _memorable and learned from_? Which matters more? Are you aware that if these motivations work together for you, _they may not, and do not, always work together for other people_?

My concern here is that your post sounds like the old saw, "when you have a hammer, everything looks like a nail". Out of love and concern you want her to change how she acts, and learn from it. But I get the feeling that your main way of doing this is "make it really hurt as much as it can, so its remembered". You've done a lot and asking for advice on more to take away or do.

Enough. 

I think you may have got caught up in punishment as deterrent and be overlooking the real possibility that communication and listening, and mutuality, works better for some people. 

It risks pushing away, someone you love, from hearing your actual message and being able to absorb it as important to them ("rebellious" as some describe it, although its hardly rebellious to ignore someone who acts as a tyrant, which may be how you unwittingly come over).

What to do?

The obvious. Talk to her. Ask her what she thinks she needs, to remember this and understand why its important. Explain your real concern and your fear that she won't heed it and will suffer badly in future. Explain how many young people feel they are fine, but later get disabling accidents or killed because they were mistaken.

Talk. Don't just punish.
