I would advise you to drop that condescending attitude, you didn't understand anything because you knew beforehand that what you were doing is wrong and you're not sorry about it either, you're just willing to lie so it can go away. Let's be honest, I was your age too. Now that we've cleared that out what you did is ,on paper, vandalism, which is a criminal offense and it's not brought up by the car owners but by the police after a complaint has been made with sufficient evidence behind it, which indeed leads to an arrest. I say on paper because I have yet to hear that a minor got charged with vandalism for egging (not saying it didn't happened just that I didn't hear about such things). If damages were done (the damages are specific to this type of action, there's a certain concentric ripple effect pattern left behind) to the cars the owners can claim the necessary repairs from the insurance company or make a big deal and blow this out of proportion and take it on you (or to be more exact on your parents). Which would be rather absurd and time consuming. However, be prepared, if they do and have serious damages to the vehicles, they'll most likely win. From my experience the most you'll get out of this is a good scare and verbal warning. Edited: I stand corrected, after reading some comments above it does seem that egging got some people arrested and jailed. However those do sound rather extreme.
