There are two entangled but still separate issues here, an over controlling dad and a law braking daughter.
Dad has gone overboard following his kid. Expecting your kid to reachable is reasonable enough, answer your phone or call back as soon as you can kinda way, but your kid shouldn't have to be ready to jump on their phone to keep you happy. Knowing where your kid is and even cheacking it sometimes is normal parenting, but electronicly following them without consent is creepy. Having a tracking devices in family cars is actually good idea, but it should be for a car getting stolen or lost and your family should know about it. Teenage comes with more freedom but it should be actual freedom as in the parents let go and let the kid do their thing while knowing that thing might mean them going for a bad idea. This doesn't mean ingnore warning signs or don't have any overseeing but you should generally trust your kid unless they have shown themselves be untrustworthy. Even if that's case you should be working toward them becoming trustworthy as they are soon adults and they need those skills.
Now the daughter otherhand, she went and did dumb. She is underage, her friend is underage, they went to a bar and used fake IDs. That's bad and you always have possibility of getting caught witch they did. Regardless how the dad found out, witch was definitely creepy way, she should take responsibility for her actions. Sneaking behind your parents back is pretty normal, especially if you parents are overbearing, but it's still not very nice and indicates that they should not to trust you. As far as outing Brad go, the dad did nothing wrong there. He didn't know and he contacting his parents clearly was just underage bar stuff, that's reasonable.
