I'm guessing that the aerodynamics could be explained by
Bernoulli's equation (which governs how/why airplanes achieve lift). In a nutshell, Bernoulli's equation states that air speed is inversely related to pressure.
In the case of car doors, I'm conjecturing that if the air speed on the outer surface of the door is fast enough, an appreciable difference in air pressure may be created between the inside of the car and the outer surface of the door -- wherein the air pressure on the outer surface of the door is lower than the air pressure inside the car. This would cause the door to "achieve lift" not unlike a large airplane wing (except that it's sideways) by opening.
