The car models origin is usually not in the CoG, so the code calculates the CoG coordinate, and sets the origin to it. Wheel positions are correctly shifted, but not the wing positions. Note, that the car bodies downforce is also evaluated at the wing positions, so the aero balance might be completely wrong, when CoG is far from the 3D models origin.

As fixing this affects car balance, the fix will be optional, thus this ticket depends on #804.

    Code to do the shifting was added in r5269. Now comes testing of 2.0 cars, and if necessary changing wing angles for humans.

    After thinking on it, I think it is unfortunate to set this feature in the human preferences, as this might result in driving a somewhat different car than the robots. So instead of setting it in the human robots preferences, it is better to only set it in car xml files, that is enable for revised or new cars, as it was done for the MPA1s or revised Supercars. A wiki page was created to describe the exact xml snippet: Features.

    For the human, r5740 comments out this feature by default, leaving the cars xml file to decide whether to use it or not. This makes it unnecessary to revise the balance of existing cars, thus closes this ticket.
