So sorry. Very scary for parents of teens (and anyone). We're just now considering letting out teen get rides home from school from other teens (we haven't let her do so yet). But, this may make me reconsider. On the other hand, children have to take risks sooner or later -- but this just made me think twice. We have emphasized over and over again to always use seat belts, never use a cell phone while driving or drive in a car when others are doing so (we never use cell phones in the car), not to distract the driver, not to be goofy in the car even if you're not the driver, how to tell someone to stop doing something while driving (e.g., talking on a cell phone, remind people to use seat belts). But it's still scary...
So sad for the family and what a horrible loss.
