Ok, now I understand what you meant, don't worry.
Have a closer look to your shot: the line is NOT at the center of the picture.
Your position, as a pilot, is right in front of the artificial horizon. If you look closely to the line, you can see that it is not in line with your head, but more on the right. The rest is all about perspective and height of the cockpit.
My advise to try to convince you: look at your keys assignements (Controls in the options) for the view controls. Find the control for moving the eye point to the right, and move until you are facing the center bar of the cockpit (what you wrote as "center wheel in real life"), and you will see that everything will be finally lined up correctly.
You get the impression that, when being at the pilot seat, you are lined up with the center line, but you're not. You're very close to it, on the left, and at some feet high. That why it's hard to see, but your position in the VC is correct
