Unfortunately, he'll prob get off scot free. Buy another car and do it again. I've seen it time and time again ... and one of those bastards killed a very close friend of mine. Similar circumstances; showing off and exceeding the speed limit twice over. My friend never had a chance
I've also watched a mate run down by a hoon and killed. These are images I'll never forget ... and I've seen these bastards in Court and they just don't care. So as mentioned above, just imagine someone close to you being killed before your eyes ... then you try to find forgiveness. I feel sincerely sorry for the dead teen's family ... no parent should be burying their kids.
Hoons who cause death should all be thrown in jail, or crush their car with them in it. I'm strongly biased on this one, so thats all I'll say on the subject.
