Motion Study: Car moves in wrong direction

Hi

I'm trying to simulate a 6 wheeled rover moving on a surface in a Motion Study. I have added just one rotary motor to one of the 6 wheels (front right), but the result is the rover still moving in a straight line. The surface and the wheels have the following friction parameters:

 

v_k = 10.16mm/s

u_k = 0.89

 

There is gravity set as well. Anyone know why the rover moves in a straight line when the expected outcome should be moving in a curve?

 

I've attached all the files.

 

EDIT: I've tried adding 3 motors on one side each turning at 1000RPM in one direction and 3 motors on another each turning at 1000RPM in reverse. The vehicle turns of 0.2s and veers off in a straight line. That's quite unexpected. Here's a video (link).

 

I've attached the motion study here.

 

Any thought appreciated.
