Restricting the wheel turn settings - I can not see that ever happening.
People use different gear, not everyone has a G25. For example the Momo wheel turns only 240 degrees, yet it is popular among sim-racers.
However, I would like to have the wheel settings displayed online, just like handicaps (ballast / intake restriction) and view options (in car / custom / chase).
This would help me distribute respect more accurately.
