Once a child becomes an adult, and demonstrates real responsibility, parents DO need to be less overbearing, if in fact that they are. Some behavior will always be viewed as overbearing, by immature teens. Some behavior WILL be overbearing, by overly possessive parents (read: Mothers).
Any rules made by parents for the reasonable safety and welfare of their children, who may be too young or immature to recognize that fact, nevertheless need to be followed. If a teen wants to be totally in charge of his/her destiny, let that teen mov out, be self-supporting,and make their own way through life. But that rarely happens that way. They want independence without actually being independent.
