What's so taboo about a deadzone setting?

I tried every other configuration to no avail. I need a deadzone increase because my Xbox360 controller is a low-quality non-precise instrument.

Smoothing doesn't help, linearity doesn't help. I need to define a larger than default centered "dead area" when no force is applied to the controller, otherwise I drive like in the green-screen movies where the actor keeps swinging the wheel left and right even though they're on a straight road...

Without a deadzone setting I can only turn, I cannot go in a straight line.

So please, either add a deadzone setting or add curve-only tracks without a single straight segment.
