I do respect your experience, and I'm open to figuring out what is going on. But to start....
Facts:
1) The steering wheel is mechanically hooked with a fixed ratio gear to the steering tie rods.
2) The car has open diffs and cannot create left to right torque without applying friction brakes.
Now, I've experienced what you have-
I've even posted about it. But this is because humans are pretty bad about torque vs position, and the fact that torque always requires some displacement. When you're fighting the rack's incorrect center, it feels like you're steering much more off center than you are. As the rack re-learns center, it's not that the front wheels are pointed in a different direction, it's that you don't have to provide anti-torque, which you interpret as a position change. You also interpret pull a lot because the car goes to one side whenever you apply zero torque.
Can you imagine the insane software required to do torque vectoring cleanly while under power, coasting, and braking, all while throwing away power as heat and killing range just so a car with a bad mechanical alignment can feel OK?
