Idea for a short story

A guy takes a long hard look at himself and realizes that life isn't worth living. He decides to end it all so he goes down to the garage, closes the doors, gets in to the car and starts it up. And he waits. While waiting to die, he thinks about his life, his family and how things led up to this moment. He sits and waits and as he is passing out he realizes that maybe, with a few basic changes, he could have led a happier life. He comes to with his wife banging on the car window, frantically shouting "Wake up! You bought an electric car, idiot!" So he takes the gun out of the glove compartment and shoots himself.
