 =================================================
 Neb car jiggling left and right
+        Happens on terrain and any other mesh object. Flat cubes are much smoother.
 Vehicles (Move smoothly)
-Light cycle falling over when driving
-Light cycle not banking
-Do single prim vehicles don't seem to properly vehiclize.
-Gun sending shooter flying
+Add vehicle collisions so IsColliding is properly reported.
+        Needed for banking, limitMotorUp, movementLimiting, ...
+Some vehicles should not be able to turn if no speed or off ground.
+For limitMotorUp, use raycast down to find if vehicle is in the air.
+Implement function efficiency for lineaar and angular motion.
+Should vehicle angular/linear movement friction happen after all the components
+        or does it only apply to the basic movement?
+After getting off a vehicle, the root prim is phantom (can be walked through)
+    Need to force a position update for the root prim after compound shape destruction
+Linkset explosion after three "rides" on Nebadon lite vehicle (LinksetConstraint)
+Implement referenceFrame for all the motion routines.
+Cannot edit/move a vehicle being ridden: it jumps back to the origional position.

+BULLETSIM TODO LIST:
+=================================================
+Disable activity of passive linkset children.
+        Since the linkset is a compound object, the old prims are left lying
+        around and need to be phantomized so they don't collide, ...
+Scenes with hundred of thousands of static objects take a lot of physics CPU time.
+BSPrim.Force should set a continious force on the prim. The force should be
+        applied each tick.  Some limits?
+Single prim vehicles don't seem to properly vehiclize.

 Speed up creation of large physical linksets
         For instance, sitting in Neb's car (130 prims) takes several seconds to become physical

 LinkablePrim class? Would that simplify/centralize the linkset logic?

 BSScene.UpdateParameterSet() is broken. How to set params on objects?
 Remove HeightmapInfo from terrain specification.
