However, when you're in an accident that causes the car to flip over a couple of times, it may cause the first door lock state to fail. If there was no second lock state, you would fall out of the car while it's spinning. In short: the semi-closed state is a backup safety feature.

Why do car doors not close all the way?
A malfunctioning or shorted power door lock motor (actuator) or a shorted door lock switch stuck in the mechanically “open” position can keep a door from closing. Check the fuses and try smacking the door with your hand near the switch and latch assembly to free up a stuck door lock motor.
Are car doors designed to be slammed?
Most modern vehicle doors do not need to be slammed with high force. However, people end up slamming the door due to carelessness or when they are in a hurry. Slamming car doors can become a habit if people do it regularly.
Why do you have to slam car door?
Automotive doors do require some effort to fully close and latch. The reason for this is simple. An automotive car door has a two-stage latch. The first position will prevent the door from opening completely.
Why did car doors change the way they open?
But back before World War II, there was a fad in the United States for putting the hinges of the rear doors near the rear tires, so the doors opened "backward." These rear-hinged doors (called "coach doors" in the auto business) had the advantage of making it easier for the passenger to enter and exit the vehicle.
