There’s a pretty good observation in the book “Iron John” that’s about how you have to take your freedom from your parents (in the myth, it’s something you steal) - if it’s given, there’s always the shadow of it being taken away again. If it’s something you’ve taken, it’s yours now.

Testing “seatbelts” doesn’t really take any freedom/adulthood for yourself.

Spending your earned money on something your parents don’t approve of, does.
