ultimately this leads to the drivers potentially incorrect steering movements, and ignoring them if they are not persistent. of course, this will all happen very quickly.
you can test it by sticking it in eco pro, driving off and quickly moving the steering wheel slightly to the left and right- in eco pro you should notice that the car ignores quite alot of the movement you're requesting.
stick it into sport, and repeat, you should notice that it responds to your every move.
the idea isnt to change the steering arc based on driving speeds- its to ignore unintended movement in the wheels....
^^ thats what i think anyway
