I didn't see this posted anywhere else -- it would be really cool IMHO if each individual person's car sound settings (e.g., Shift-A) were reflected in multiplayer games. So with a race full of FXO's, each one would sound a little different based on the "tuning" each person had done.
A pretty minor thing, with no impact on racing at all, admittedly, but it would add another level of customization to your own car
