A car shouldn't "keep the turn radius", they normally drive straight by default. The forces acting on the wheels do that automatically.

It doesn't seem like a wrong thing, to me.

I think the line is quite obvious between the physical comfort features and the mentally disengaging features.

GP said s/he didn't understand why anyone would want these in-betweens. I gave an explanation as to why.

Based on what you're saying, it seems the divide arises from some drivers classifying these features as physical comfort, and some as mentally disengaging.
