Re: [Torcs-devel] xbox patch

a question somewhat related to this email:

Is it possible to set the controls so that the amount of wheel turn is
proportional to the speed of the car? I.e., when the car is running very
fast, the larger turns of the wheel would be needed, but when the car is
going through a slowly curvy section, the steering wheel is more sensitive
to turning. I believe this is the behaviour in some comercial cars, not sure
if there is a term for it...
