Would it not be a good idea to have a brake somewhere near the green ball-bearings so that when the "diff" disengaged the left-hand track is stopped? In one of my many "robot" variants I had a version that had 2 tracks, steered by cutting the power to 1 track rather than using a H bridge to lock up the unpowered track. I found that the vehicle still wanted to go in a straight line even though that ment turning over the unpowered motor.
There is also the problem you got on Valentine tanks, which used exactly this form of differential and had a brake. If you were going downhill and disengaged the left track- as in your example- without engaging the brake the tank steered right rather than left, as the left track simply ran away down the slope.
