When a car turns to the left, it is undergoing a form of rotation, describing a 90°-angle or one-quarter of a circle. Your body experiences inertia, since it was in motion along with the car at the beginning of the turn, and thus you tend to move forward. Thus the car door itself is moving to the left. As the door meets the right side of your body, you have the sensation of being pushed outward against the door, but in fact what has happened is that the door has moved inward.
