I'll entertain your questions this once. The child was happy when she got her driver's permit because she was the first from her group of peers (and people he hangs out with) to get it. To date, they still don't have their permits.
We learn about her outings after the fact, through people we know that are reliable sources of info. Dad has approached both mom and daughter about it. Daughter screams and curses, and mom blames dad for having left her and steers away from the child's issues. (BTW, I have nothing to do with their brakeup and met dad long after they split) Mom and child do these things without informing dad, so being that he is not the custodial parent he is out of the loop.
Dad doesn't want to file for full custody because daughter doesn't want to live with him and has threatened to run away or hurt herself. She has, however, agreed to go to counseling with dad, so that's a step in the right direction for them. The only thing I think should happen further is for mom to joing the counseling sessions because she and dad need to agree on how to handle their child without undermining each other's authority. But that's up to them. I'm really not trying to get too involved because, although I care for dad and daughter, the reality is that I'm just a third party in this situation.
