I suggested this several times, but never got heard (I think)
In the PS2 Version of Richard Burns Rally it was like that. You configured the Game to i.e. 540 Degree Lock and then when you reached 540 Degrees the Wheel stopped because of some constant Force that was applied by the game.
If you reached the end of 540 Degrees I COULD turn it more because I am MAN and MAN is more STRONG than WHEEL *ugh*! illepall
But even when driving a Rally car very wild the Force applied at the 540 Degree Lock was strong enough.
THIS in LFS and the DFP / G25 support would be perfect. It´s just annoying when you have to look at the Wheel on the Screen to see when you have reached maximum Lock
But S2 is not finished yet and I have some hope :-)
