Car-Fu: The Ancient Art of the Car Chase (2003)

From the Introduction

Your standard, Hollywood car chase is to Wushu-style Car-Fu as your standard, Hollywood fight scene is to Hong Kong-style wire-fu: boring and pedestrian! One of the unique advantages to role-playing is that you are not bound by physics, budgets, or concern for anyone's safety. Car-Fu is about using that freedom to create impossibly acrobatic car chases packed to the gills with over-the-top stunts, death defying jumps, and enough property damage to bankrupt a major insurance company!

This expansion was created for the Wushu narrative system. It can be found at DriveThruRPG.com
