As Captain Willard famously said, "Never get out of the boat."

It's good to have rules and follow them, but it's also important to have a strategy for what to do when plans don't seem to work. One important strategy is to question what you believe are the facts of the situation, and then take action if the other party doesn't appear to be acting as expected. If Nancy or her husband had realized she could have accidentally passed him, they could have acted accordingly and flagged down drivers going in what intuitively seemed the wrong direction. A good lesson learned for all of us.
