Setting in GPL for Linear vs. Non-Linear

    maybe I'm missing something in the translation of Linear and non-linear.
The way it looks in GPL, with the slider all the way to one side the
steering wheel turn and the front wheel turn is (exaggerated view) matched
1:1 till the steering wheel is as a certain point.  The  ratios are changed
to a 1:5.  With the slider set to the other side, The ratio starts at a 1:5
and ends at 1:1.  with the slider set in the middle, it starts as 1:1, then
goes to 1:5, then goes to 1:1 as the steering wheel is still turning in that
one direction.  The slider just determines where that ratio change takes
place.

    Again, My idea of what is happening may be wrong.  If I'm right, Then
getting rid of that all together for a wheeled system (as opposed to a
joystick system) and building a wheel that can turn more then 360* in one
direction would help.  If I'm wrong with the above concept of linear
sliders, then I need someone to explain what is happening.

You've never watched in-car of Mark Martin or Rusty Wallace, have you?  They
both reposition their hands in the turns - at least on the short tracks...

Most of the guys back in 1967 did do that.  They still teach the method in
racing schools.  Lots of Rallying is done using that method, even in today's
small steering radius racing.  Stockcars, with big'old steering wheels also
use that method at various tracks.  I did it on my old wheel, but I now
completely changed my style to adopt only a 90degree limit on both sides.  I
personally think that if I perfect my method on such small lock, nothing
will prevent me in the future to go with bigger wheels or longer wheel
travel on each side.

Gonna have to try that guys, seeing as everyone seems to agree on this.
