My primary goal of this experiment was to try out driving such a vehicle on Logitech G27 wheel. But since quite a good reception, I'm going to proceed with develoment of this mode up to "production" level.
Latest version - 0.1.2
Currently in development: Advanced bellow jbeam, for wobbling, collision, tearing, etc.
and Bi-articulated version with rear-axel drive, for specifically challenging driving:
Select "Articulated Frame" in the Bus components list to try out.
Experimental Articulated Frame component for Bus 0.1.2.1
not so quick but still dirty experiment
