I Momentum, axes, and tires

    A car traveling north makes a right turn, to head east.
    How do the tires completely offset py and simultaneously create px?
    (If the tires merely acted like guidance jets, it might turn to face east but continue traveling north.

    The frictional force between the tyres and the road starts the Earth moving north and west. Since the Earth is a lot more massive than the car, the movement is very slight.
