I see a lot of "door popped open" stories.
I've had airplane doors pop open on me.

Stories of automobile doors popping open seem to be much fewer.

My conclusion:
Past designers of small airplanes had no f'ing clue how to design door latches.

(I read somewhere that auto manufacturers spent a lot of time and money to get that distinctive door closure sound that gives the needed feedback indicating proper closure.)
