ah the invincibility of youth. im sure most of did stuff that smart when we were those ages. some day you will realize that your not the only one on the road that your driving can effect. enjoy it why you can and good luck with it not going wrong.
I actually do it when there isn't cars on the street...common sense and I do know I could crash but that's not only me there is other drivers on the street that don't even know how to drive or are careless thank you=)
