I'm going to think this out logically. You obviously feel a great deal of remorse for what you did, which is good. You still have a moral standard (even if you broke it), and a soul left. You know what you did was totally irresponsible and dangerous. I truly hope it SCARED you enough to never do something like that again. Now, ask yourself this question. If you truly feel that bad about the car and your broken trust with your father, should you be driving it? If you would like to continue to drive it and learn from your own mistakes, then I suggest you man up and take responsibility for what you have done. I'm not sure I would tell him about the drunk part... The reckless driving might be enough without the Alcohol factor. You know you messed up, but if he doesn't know about you drinking, then I would leave that part out. Just tell him you were acting the fool and lost control of the car being stupid. I trust that your own conscious will keep you from drinking and driving again...

BTW, are you even old enough to drink???
