Options > View > Look Function, set to "Steer".
I can't drive with that on, it's too hard to tell whether the car is oversteering or understeering. It's also hard to keep track of a car on your outside through a corner.
Edit: Just in case I misunderstood you: The driver's head model turns when you turn anyway, so it will always look like that from outside the car. The above option (probably obviously) controls how your view changes when you move the steering wheel.
