Out of Gas<br>Tom was driving around. His gas needle didn't go down. Tom didn't realize something was wrong. Eventually his car broke down. Tom re filled and fixed the gauge.
It's possible that Tom's car broke down while someone else was driving it.
It is definitely POSSIBLE that someone else was driving when it broke down, because the story states that "eventually it broke down" - which means it wasn't necessarily while Tom was still driving the car.
