If you build or use vehicles you know they have been having region crossing problems. According to reports in the SL Forum things are much better in Magnum regions.
Andrew Linden explains what they found and worked to fix, “The problem was caused by the new Interest List code which tries to not subscribe to objects that are outside of the camera view. When crossing a region boundary your viewer would extrapolate your camera forward, the vehicle would be created behind the camera, and the server would not subscribe to it. The faster the vehicle the more likely this would happen.
The solution was to special case Interest List subscription to whatever you’re sitting on — the server now ALWAYS subscribes to your seat. We already had some special case code for seats, but it needed a little more.”
