The security guard is doing his job and is the hero of his own story (in fact has an extra on DVD about his family.) He is trying to get the 'villians' to stop. Austin Powers is the hero in his story because he is just trying to get to the other side of the room to stop Doctor Evil. The vast gulf between the two is just how far apart and how little danger there really is. It is also a story about how avoidable the inevitable crunch at the end is.
- The guard could have stood to the left or right and let the steamroller go by. [The guard could have also shot Austin or something else.]
- Austin could have 'swerved to the left or right' just a little and missed the guard. [Or he could have gotten out and gotten there faster.]
