Narrator: A train is designed to travel in one direction only, forward. Its path is forever dictated by the track beneath it. It has no choice. Thus, collision with other trains is avoided. The car on the other hand, is designed to maneuver in infinite directions. This is not a problem until other cars are added to the equation. They, of course, are also moving in infinite possible directions. Indeed, on one road at any one time there may be thousands of such creatures, each moving on their own individual path. Collision, therefore, can be delayed by the careful driver, but eventual contact is inevitable. Thus, it is in the nature of automobiles to crash into one another. Their very being, their very freedom dictates it. Some companies have known this fault since the car was first invented, and they have sought to find a cure, at whatever the cost.
