From the introduction: The RHAD Rules are an alternative system of rules the Red Hook Autoduellists adopted back in the early 90's to make handling count for something and yet not sog down an evening with its mess of details. The RHAD Rules are quick and simple yet still carry Car War's treasured feel of realism. User summary: The RHAD Rules are intended to replace the turning, drift, and crash rules from the base game with streamlined rules. The new rules are purely mechanical with no roleplaying alterations.
