The Concept of intelligent Vehicles has been gathering momentum for some time over the last decade. The Intelligence of an autonomous Vehicle can be broken down into three kinds of behavior. The Overall Motion Plan or the Active intelligence which takes into account the entire structure of the environment before planning the motion path, this can be called the mission oriented intelligence. The Reactive behavior or the immediate plan of action which allows the Robots to navigate immediate impediments to their mission oriented behavior. And Finally, Environment Adaptation which allows the robot to comprehend the changes in the environment, localize itself in the World Space Model and use its active and reactive intelligence accordingly.

This is primarily the Navigation intelligence Pattern which can be commonly observed in almost all autonomous vehicles in a broad sense. The priority order for all three of these is variable depending on the exact nature of the mission the autonomous agent is supposed to perform. For Example in a Pathfinder exploring unknown environments you might have a different priority than in a Racecar Bot, which will have a lot of prior information to work with.
