There was a perfect man who met a perfect woman. After a perfect courtship, they had a perfect wedding. Their life together was, of course, perfect.
One snowy, stormy Christmas Eve this perfect couple was driving along a winding road when they noticed someone at the roadside in distress. Being the perfect couple, they stopped to help.
There stood Santa Claus with a huge bundle of toys. Not wanting to disappoint any children on the eve of Christmas, the perfect couple loaded Santa and his toys into their vehicle.
Soon they were driving along delivering the toys. Unfortunately, the driving conditions deteriorated and the perfect couple and Santa Claus had an accident.
Only one of them survived the accident. Who was the survivor?
The perfect woman.
She's the only one that really existed in the first place.
Everyone knows there is no Santa Claus and there is no such thing as a perfect man.

So, if there is no perfect man and no Santa Claus, the perfect woman must have been driving. This explains why there was a car accident.
