Currently, Each vehicle is simulated on solely one core. This means Things like the T75 require extremely high clock speeds to run well, and trailers make the fps even worse. If there was a way to simulate a beam between threads, it would allow wheels to be simulated separately from the rest of the vehicle, or other FPS hungry parts like trailers too. I'm aware it probably would be difficult to keep everything in sync, but if it can be done the benefits would be undeniable.
It's on the ToDo list, but it's not easy to add. But if they managed to do that in RoR, it will come at some point in BeamNG as well..
