It is very Simple .
STOP the Car or drive slowly. Try to make a U turn ( max stearing to left ).

If you have the active stearing you should be able to turn your stearing wheel about one time. (Front Straight to MAx Left).

If you don't have it , you will need to rotate your stearing wheel about 2x.

Above 90km/h (60mph) their is almost no difference (expect Safety feature with ESP).
