Hi, not many games really have the head turning while driving unless it from another view point. You could add more view points.
Examples:
Through window
No window view
Bonnet view
Above car
Dash view
Also there would have to be another key press to use turn head in car option. But would not need the extra key while stopped but they are still in car.
If you really wanted to give a great option you could add mirror view too, rear view, and side mirrors too to see what's behind them.
