If you haven't experienced the sudden opening of a door you won't plan for it properly. You can't avoid it as there's no time to look behind to make sure it's safe to swerve out in front of possible passing cars.
There is an immutable law that states that this only happens once to a cyclist. After the first experience a cyclist never rides along a row of parked cars within the metre that is a car door span. When it happened to me, l landed fairly comfortably in the drivers lap. As the driver helped me out she was as shocked as I was and just kept repeating, "Oh I'm so sorry, my boss cycles to work every day." I'm not sure how comforting she meant this to be, but it didn't help straighten my front wheel.
