Reggin, you need to refrain from making very broad assumptions and stating them as facts.
From what I understand, we know a lot about the structure of the brain, but this does not necessarily tell us more about functions of the brain. Yes, I think it is common that teenagers take more risks because of the immaturity of their frontal cortex, because that is where the brain reflects on things and reasons in regard of certain behaviors. But just saying that "the brain is not fully matured" by age so and so and that is why teenagers behave a certain way they do cannot be said like that because it is way more complicated.
Plus, from what I remember, experts have said that brains do not fully mature until the mid 20's. So scratch the 17 or 18. And then there are so many factors that come into play on an individual level.... I think it really depends on the person.
