Well, it's sad, but there's not much the biker could have done for his passenger, even if he had stopped. It's also very possible to not know you're lost your passenger. When my wife rides with me, I reach back every few minutes and grab her calf, just to set my mind at ease. On a hwy. with no real handling or steering issues, you might not notice the weight difference if someone on the back fell off.
