A few weeks ago my friend was in a serious motorcycle accident. It was just a casual day of riding when he crashed into a car. He's very attentive and rides defensively, but it happened out of nowhere to the point he has no recollection. The driver of the other car quickly covered him up at the scene and got him flowers the next morning.
No matter how attentive you are even with little to no distractions something like this can happen out of nowhere.
