+1; Time will tell what happened as there should be enough data onboard. These systems are essentially in training mode and new scenarios will need to be accounted for.

I am curious as to why the driver didn't react. I wonder if the system keeps track of the driver as well as I would imagine it has to be mind numbing to sit behind a wheel for hours on end and not do anything... So in this situation, how attentive and alert was really the driver who is supposed to be the fail safe mechanism.
