The problem with the doors is that unlike all the other traffic scenarios you could be involved in they contain some surprise elements. For one it is stopped traffic (something that is normally safe) that suddenly becomes dangerous, also it can happen very suddenly. One moment a car is an immobile object, the next it throws a 3' obstacle directly into your path, and if you're close enough there simply isn't time to react. It's next to impossible to safely avoid a door if you are less than your stopping distance away from the door when it is thrown.
After all, taking into account that hitting a door is bad it is arguably less bad than trying to avoid it by swerving around it and getting clipped by a car behind you that doesn't respond in time (assuming it even has room and time enough to respond). Ironically, electric vehicles are more dangerous in this sense than combustion powered ones because they are extremely quiet.
Every time someone in my car is about to open any doors I automatically say 'careful for bikes and pedestrians'. Some people are annoyed by this but I still do it and it has already saved the situation more than once.
I'm currently recovering from a one-sided cycling accident so you can take that as proof that cycling is a dangerous activity, no matter what (right leg broken in 6 places, 2 chunks of steel and 13 screws later and I can re-learn how to walk, the accident happened Aug 7th, I'm already back on the bike and driving but it was a tough battle to get to this point this quick).
