Newton's third law problem.

Let me know if you see the image and if you agree with the lever option as analog to that vehicle.

Sure it can. Just swap the gearing ratio, and replace the rubber band with a non-springy belt.

All materials have elastic and plastic deformation in real world so you can not get rid of that.
You can reduce the size of energy storage but that is irrelevant the frequency of charge discharge will increase and it will still work the same way.

Please, try it. I'm not tricking you. I showed you math that *proves* it works. The only reason for you to not try it, would be to avoid being proven wrong. Keep your mind open, friend, and try it.

See attachment and let me know if you agree with that analogy.

I won't tell you, before you actually retry the experiment with swapped gear ratio, and describe your observations here.
It is a very small, simple thing for you to do, after all. You've already posted videos of two variants above, so how much more effort would a third one be?
Or is it that you did it, and observed exactly what I said you would, and are now annoyed that your model is broken?
I'm not doing this –– responding here –– because I want to break your model, or break anything at all.
I am responding here only because I want you to have a *working model*.
Please understand that.

I tested all variants and there is no difference the vehicle works the same way with charging and stick slip hysteresis as there is no other way for the vehicle to work.
Please see that attach diagram and let me know how is not that a locked system that will not be able to move to the right without both energy storage and stick slip hysteresis and to the left without slip.

The vehicle has only two points of contact.
Front wheel the one of right sits on a treadmill witch can apply a force F1 to that wheel
Back wheel the one of the left is on the ground (red box is connected to ground) same as treadmill body witch is also connected to ground.
The question:
a) What will happen in a theoretical case? where there is no wheel slip and no components can deform in any way elastic or plastic including the belt.

The vehicle will move to the right, obviously.
Until you can see that, your reasoning is defective, and many things you try to deduce with your defective reasoning will be wrong.
The reason nobody will debate with you is not because it is boring, but because it is pointless. Since you cannot, or will not, understand, there is no point trying to explain anything to you.
