It doesn't suck for you.
Both you and your parents are retarded. Why would they let you drive a car unsupervised? Why the heck would you want to ask them to let you drive at 13?
I am glad your safe, but you were quite stupid to ask them, and they were equally to blame for letting you do it. When I started learning to drive, I had parental supervision 100% of the time in the vehicle. I have yet to have a major accident.
Back from the dead, I'm afraid.
