Coincidence?

I love stories of possible coincidence that ended up being a life-saving moment.  One such moment happened yesterday to Shelley.

Shelley is a nurse practitioner who was on her way to "Bed and Bath".  She set her GPS for the address where she was going and headed off to her destination.  When she reached a certain point, her GPS told her to turn left when she was pretty certain she was supposed to turn right.  Tending to believe the GPS, she turned left and drove out of her way for 2 miles before deciding the GPS was wrong and u-turned to retrace her steps.

In less than a city block, she witnessed a car crash into a tree. She could see a figure inside the car that wasn't moving so she rushed over to do what she could, telling a young man at the scene to start breaking windows to get the driver out.  This was very important because smoke was beginning to come out of the car.

The young man was able to break into the car and helped remove the unconscious driver so Shelley could perform CPR on him.  When she started he had no pulse and wasn't breathing but she was able to "restart" him.  When paramedics arrived, Shelley stepped aside and let them do their work.  Apparently the driver stopped breathing again as they loaded him into the ambulance so we don't know if he survived.

The point is...what intervention occurred to have Shelley's GPS send her 2 miles out of her way where she would see an accident and be present to offer medical attention?  This story gives me chills to think how many times in our lives, accidental occurrences result in a most favorable outcome.

Was this just a coincidence?  I honestly don't think so and it reinforces my belief that there is some kind of guidance and plan for our existence on this planet.  Not being religious, it's difficult for me to make logic out of this but it is what it is...and I doubt very much that it was coincidence.

Update:  Shelley hunted him down at the hospital he was taken to and he is still alive but in an induced coma.  She met his family who had been told of her involvement in saving his life and who were very grateful to her.  It still remains uncertain if he will recover but I'm thinking all of this didn't happen just so that he'd live but a few days more.  I think he was saved for a purpose and it would be interesting to learn what it was.
