You don't need a setting for the wheel offset. There is only one place you would want it, which is out of the way of the dials. I can't see why someone would want it in front of the dials. You don't need to adjust the wheel position for physical reasons like in real life either. The dashboard could maybe be re-designed so that the wheel wouldn't block the dials.
As for moving the mirror upwards: If you set the mirror offsets to 0, the mirror is where it would be in real life. It looks like it's too low, but if you look at it from the outside and/or measure where it is in your real car, it's in the correct position. Moving it up would actually make it go through the windshield.
