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 - 0.1.2.3
Select "Articulated Frame" or "Bi-Articulated Frame" in the Bus components list to try out.
NOTE: "Bi-Articulated Frame" lacks interior and engine cover due to 10000 beams limit.
In development: making these three parts as separate vehicles, which will allow to have them completed with interior and axels powered by electric motors, as well as to have ability to build even longer "trains".

not so quick but still dirty experiment
