1201 // of the yaw effect will be proportional to the
1202 // VEHICLE_BANKING_EFFICIENCY, the angle of the roll rotation, and sometimes the vehicle's
1203 // velocity along its preferred axis of motion.
1204 // The VEHICLE_BANKING_EFFICIENCY can vary between -1 and +1. When it is positive then any
1205 // positive rotation (by the right-hand rule) about the roll-axis will effect a
1206 // (negative) torque around the yaw-axis, making it turn to the right--that is the
1207 // vehicle will lean into the turn, which is how real airplanes and motorcycle's work.
1208 // Negating the banking coefficient will make it so that the vehicle leans to the
1209 // outside of the turn (not very "physical" but might allow interesting vehicles so why not?).
1210 // The VEHICLE_BANKING_MIX is a fake (i.e. non-physical) parameter that is useful for making
1211 // banking vehicles do what you want rather than what the laws of physics allow.
1212 // For example, consider a real motorcycle...it must be moving forward in order for
1213 // it to turn while banking, however video-game motorcycles are often configured
1214 // to turn in place when at a dead stop--because they are often easier to control
1215 // that way using the limited interface of the keyboard or game controller. The
1216 // VEHICLE_BANKING_MIX enables combinations of both realistic and non-realistic
1217 // banking by functioning as a slider between a banking that is correspondingly
1218 // totally static (0.0) and totally dynamic (1.0). By "static" we mean that the
1219 // banking effect depends only on the vehicle's rotation about its roll-axis compared
1220 // to "dynamic" where the banking is also proportional to its velocity along its
1221 // roll-axis. Finding the best value of the "mixture" will probably require trial and error.
1222 // The time it takes for the banking behavior to defeat a preexisting angular velocity about the
1223 // world z-axis is determined by the VEHICLE_BANKING_TIMESCALE. So if you want the vehicle to
