"I was driving. Driving my car. Driving down the highway. I saw an exit that had a mechanic. So I pulled off of the highway. But that wasn't my intended destination. And it wasn't something I did on a whim. You see: There was something wrong with my car."
Then there was the chorus, which talked about how sometimes you have to make decisions, and you only have microseconds to make them.
The rest of the song alternated between that chorus and other similar speeches in which mundane decisions are described with excessive drama. But I don't actually remember those parts of the song.
