[ODE] A problem about Wheel Turning at a high speed

[=?GB2312?Q?=C1=D6=BD=AD?=]

Hi,All:
		
	Our Racing Game meet a strange thing: when at a low speed, Turning the wheel is very easy and normal,

	but when the car speed up to a high speed,  Turning the wheel become slow and hard ,why so?

	( Our Car is four-wheel, Back wheels to add motor and front wheels to steer ,both are Hinge-2

	joint which connect chassis and wheels )

	Thanks.
