Symptoms

Assetto Corsa Rally appears to read a controller as a steering wheel.

Reproduction

1. Enable wine-wayland via PROTON_USE_WAYLAND=1 flag. Optional - pass PROTON_USE_SDL=1 (explained later).
2. Launch the game.
3. Enter Settings -> Inputs.
4. Attempting to bind any gamepad action, results with the game show a warning saying "this input cannot be bound to this device category". Using the same input in "Racing Wheel" category, creates a binding. Examples:
   Left Stick Horizontal Axis - Analog2
   Left Stick Vertical Axis - Analog1
   Right Stick Horizontal Axis - Analog4
   R1/Right Bumper - Button6
5. If using SDL via PROTON_USE_SDL, my controller is being read as both a gamepad and a steering wheel. I can now navigate the menus, however I can still bind my controller as a steering wheel. This is still an issue, as I cannot drive a car during a race, as this game defaults to the fake steering wheel input, which is waaayy too sensitive and does not allow adjusting a deadzone.

have you tried proton experimental?

[TakinaLisa]

Yes. Controller input works as it should, possibly because Steam Input is taking over the control over gamepad input, and/or it's running in Xwayland mode rather than pure Wayland
