"Dutch Reach", sorry I'm not Dutch. Personally, as a motorist and an ex cyclist, when I open my drivers door I check the door mirror first and as I open the door and look in the mirror the field of vision increases as the door opens, once the door is open slightly I can the look through the gap. I also make sure that I've got hold of the door firmly incase it's windy and the slip stream from passing vehicles.
Motorist have to leave 5' when passing cyclists so cyclists should surely leave room for a potential door opening, and if observant notice that the door is slightly open and adapt accordingly.
At the end of the day it should all be common sense, ha, that shows my age, common sense doesn't exist anymore these days. It's a mad crazy, sue you world we live in now,
