Compared to steering with the controller's lever, it is definately better if we can drive with the real steering wheel. But what if we can't afford to buy a G29 but we do have a PS5 controler? Maybe we can steer with the controler and use the trigger as the pedal, just like the GT7 did. Hope you like this idea.
Should be able to do so with DS4Windows: "The Gyro tab contains the gyro settings and allows you to assign specfic commands to certain tiling actions." You could probably hook up the roll as an axis.
