i used to run out in the driveway and stop my ExAH. Hide the keys. Rage. Lecture. Feel superior. I realized years later I shouldn't have tolerated it even once and broken up with him cause normal people don't put up with that stuff. The real answer isn't turning them in, it's getting that insane, risky behavior away from you and yours. Turning them in will only suck for you too cause you'll still be wrapped up. You'll pay the fine. You'll drive him/her around. You'll suffer but in a way you'll have it coming because you stayed with him. I mean "you" in a general way, not you specifically.
