Whether or not anything moves has nothing further to do (beyond its application to these force pairs) with Newton's third law.  So you cannot keep using it as the reason why you think that everyone else is wrong.

Can F2 be different than F1 in a non accelerating reference frame and if so what will be the relation between F2 and F1 ?

If you are not able to provide that relation and insist vehicle moves then you did not understood why it moves.

F1 will not accelerate the vehicle thus F2 equal and opposite to F1 else F1 can not exist according to Newton's 3'rd law.

In non accelerating reference frame in case (a) F2 = F1 and the real tests confirm that is the case.

I'm no longer sure what you are confused about. Is only that vehicle is a "locked gearbox" so thus can be treated as a single solid object or even if that was the case you still do not agree with the fact that F2 is equal and opposite to F1.

F1 may or may not be equal to F2, but they do not constitute a Newton's third law force pair.

If you assume that the vehicle is not accelerating, then Newton's second law will tell you that F1 is equal and opposite to F2 (if you ignore any frictional effects). And if you assume that F1 is equal and opposite to F2 then Newton's second law will tell you that the vehicle will not accelerate.  But you cannot prove that the vehicle will not accelerate this way.

Newton's second law has no application in a non accelerating reference frame.

Videos I showed you multiple times show that F2 = F1 and there is no acceleration.
In order for vehicle to move relative to ground one of the wheels needs to slip.

1.  No wheel slip F2 = F1 according to Newton's 3'rd law.

2. Left wheel (output wheel) slip during acceleration period F1 = F2 + (m * a) thus both 3'rd and 2'nd law are added and F1 is larger so vehicle moves to the left (it is dragged to the left as there is no wheel rotation).
After acceleration stops and vehicle is dragged at constant speed F2 = F1

3. Right wheel slip  F2 = F1 while energy storage is charged so right wheel rotates but vehicle is not accelerated then stored energy is converted to vehicle kinetic energy F2 = F1 + (m * a) again both 3'rd and 2'nd law applies this time the acceleration is due to stored energy and so vehicle moves to the right.

All 3 cases where demonstrated in my videos showing the real world experiment.
Notice that in none of the cases the F2 = 2 * F1 that will be the case for a 2:1 gearbox. But there is no working gearbox as that requires 3 points of contact and will not work with just 2.

Seriously? Another one of these threads? Why do you guys waste time arguing with a troll? He never posts anything except for nonsense like this trying to stir people up.

The troll seems to be you. You have nothing to say but decide to comment anyway.
