Sadly as it is at the loss of life, I can't help but wonder if the ruts in the road had anything to do with the Honda crossing over into the other lane?  I know from experience that ice in the ruts will throw a car to the left or right if the right conditions are present.  The Glen and Seward Highways are the worst, heavily traveled roads are just as bad with small to medium ruts.  It worth taking a look at.  Any other opinions out there?
