    These are the values I put in for my own use (“sled physics”)
    My request is that someone “upload” this in scs file.

    # These coeficients are used for computing autocentering wheel speed.
    # The faster vehicle moves and the more steering wheel is turned left or right
    # the higher autocentering speed is.
    # Given value of speed_coef is for 100km/h velocity (linear raise).
    # Given value of angle_coef is for maximum wheel turn (30degrees, linear raise).
    # Returning speed coeficient is computed by multiplication of both coeficients.
    # When result coeficient is 1, returning speed is exactly the same as full
    # turning speed. This balance points define natural limits of steering
    # dependent on vehicle speed.
    # Ratio_coef defines upper limit of result coeficient (ratio against player).
