Wow. The new /changed details (possible phone use at the time of the accident, possibly no oncoming traffic) are...troubling. I have a very long drive to and from work, and see plenty of craziness every day. And plenty of accidents every week. It's too easy to lose track of exactly how much energy is involved in moving two tons at 40-70 mph and what the potential outcomes are for anyone in a driver's viscinity or path should something 'go wrong'. Driving is dangerous enough if done responsibly. That's not necessarily to place blame in this case as I don't have all of the facts here, more as a general comment (to the choir I'm sure).
The balance of repercussions could use some work.
