Self-non-closing Doors

A few times now I've walked into my daughter's day care, through the building, and back around to the playground area only to see my driver door wide open.

After a few days of paying attention to the car's behaviour (when it usually closes, and where I am standing when it does) when self-close was working, it was clear to me that these were definite failure cases and not simply me not waiting long enough. Some additional testing showed that I can reliably reproduce the effect by exiting the car as the door opens and moving mostly perpendicular to the car (i.e. continuing out of the door and away from the car, rather than towards either the front or rear of the car).
