Have you ever looked at an LST enabled scenery, and seen a car drift a corner? Just sliding along a straight line as it's heading changes... seems rather dangerous! But it was simple, just interpolate the headings in between route legs.
But... no more! LST V1.11 now smoothly, properly turns cars cutting corners while making smooth turns, rather than making them drift. In addition, there are also numerous bug fixes, a new PCL system developers can implement, a new dataref developers can use to easily de-sync animations, and, of course, more bug fixes! (though, I can't promise I haven't added any more haha)
So, be sure to head on over to X-Plane.org and update your copy of LST!
