I agree with all of what you said. Some people here seem to argue that every last decision should be made by 'adults' until said people turn 18 (or some people seem to think 20 or older in this thread...) and then all of a sudden throw them off on their own, to suddenly have to be adults- whether that means moving into your own place or going off to college and living in a dorm, or by definition of being 18, or whatever.
I don't know how everyone else grew up, but I'm going to take a wild guess and say that as we went through our teens, we got more and more freedoms in terms of making decisions about things without consulting parents or having parents know every detail of what we did. Many people get their drivers licenses the minute they turn 16, as you mentioned. They typically are working part-time and have to be responsible to actually show up to work and do their jobs. Your mother is not determining your work schedule. The in-betweeners are able to stay home alone without babysitters or someone watching their every move. They get curfews and are able to go out with friends on their own, etc. If anyone here on FSU had their parents making every last move for them until the minute they moved away/out, I'd love to know how they did in that first year or so of being on their own.
Also, I don't remember if I said this in the open or not, but I was kinda

about the meltdowns regarding texting. When I was a teen, cell phones were just starting to become commonplace for everyone, and there was a limit on texting. My piano teacher definitely texted me quite a bit, and I didn't and don't see the problem with it. Any boss that would be texting or calling me- same thing.
Even though the argument keeps going in some kind of circle, Anna made it very clear that her family and her coaches were indeed concerned for her health and checked in with her quite frequently (which doesn't fit the original mindreader narratives), but ultimately they were ready to listen to how she felt.
