EldE 98 incorrect control

EldE 98 has issues with control.
The trailer unit should always follow the tractor unit the same when I move forward or back side.
If I press W+A traileris following tractor unit. It should work the same way for S+A, tractor uniti following the trailer. IS THE SAME WITH TRACTOR K - 700.
Play some “Snowrunner” game to understand how it’s working because the the tractor unit it’s coming too close to the trailer unit and the caterpillars tread are going into each other when machine stays in high angle. It works in a completely wrong way guys!

This is articulated steering it works by bending the machine at a pivot point, usually controlled by hydraulic cylinders. It works like muscles when I press W+A it should go left and forward, if I press S+A it should go back and left. It’s completely wrong in the game guys it works absolutely horrible in the game.
