i get you're angry but maybe in his eyes, your son was somehow in the wrong in driving.
I don't see any thing wrong with him wanting to go to court, he has a right to. Even if he was wrong, and since he was wrong, theres no point to be upset.
I wouldn't really stress over it. It's really boring. I've done it in high school because of an old lady who was blind. (no she actually could not see, why was she driving...).
It also doesn't take too long, it took me about an hour being in the court room.
my dad went with me.
