[ODE] rolling towards outside of curve?

In the real world, you roll to the right when turning left. 
That's centrifugal forces pulling on the chassis. The ODE 
simulation thus seems to behave correctly.

Dear all,

In my car simulation based on ODE, I notice that the
car rolls to left while turning right, and vice versa,
i.e. the car always rolls towards outside of the
curve, which seems to be opposite to our real world
experience. The road here is simply flat in my
Although the roll angles are very small and it is not
obvious from visual observation, this behavior can be
verified by taking the rotation matrix and converting
to Euler angles. Is this wrong or am I wrong?
