Mind warp

A perfect man, a perfect woman meet and get married. They have a perfect honeymoon and live together for 5 perfect years. One year on Christmas Eve, they see Santa by the road and pull over to give him a ride. Later they get in a wreck. Who lives? Well since nether Santa nor a perfect man exists, the woman does. However the woman was driving imperfectly so the perfect woman doesn't exist. Therefore no one was in the car.
