+CURRENT PRIORITIES
+=================================================
+Eliminate all crashes (DONEish)
+        Editing/deleting physical linkset (DONE)
+        Border crossing of physical linkset (DONE)
+Enable vehicle border crossings (at least as poorly as ODE)
+        Avatar created in previous region and not new region when crossing border
+        Vehicle recreated in new sim at small Z value (offset from root value?)
+Calibrate turning radius
+limitMotorUp calibration (more down?)
+study PID motors (include 'efficiency' implementation
+        Add to avatar movement

 VEHICLES TODO LIST:
 =================================================
+Border crossing with linked vehicle causes crash
 Neb vehicle taking > 25ms of physics time!!
 Vehicles (Move smoothly)
 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.
+Cannot edit/move a vehicle being ridden: it jumps back to the origional position.
 Neb car jiggling left and right
         Happens on terrain and any other mesh object. Flat cubes are much smoother.
         This has been reduced but not eliminated.
 Light cycle falling over when driving
-For limitMotorUp, use raycast down to find if vehicle is in the air.
+Implement referenceFrame for all the motion routines.
 Angular motion around Z moves the vehicle in world Z and not vehicle Z in ODE.
         Verify that angular motion specified around Z moves in the vehicle coordinates.
 Verify llGetVel() is returning a smooth and good value for vehicle movement.

 LINKSETS
 ======================================================
 Linksets should allow collisions to individual children

+Should taints check for existance or activeness of target?
