Was he in the left lane, then turned right from the left lane? I 'm thinking that you are lucky they are calling it 50-50 as the damage appears to be on the passenger side of the vehicle, indicating a turn from the left lane, across the right lane of traffic.

Some of the claims guys can answer up their idea, but it sounds like 75%+ fault for your son for making an 'unsafe' turn.
