No apparently people teach that you open the door, stick your face out in front of the oncoming bike instead. Or try squint past the door pillar and the headrest?

I really like my door not to have dents, scratches and blood all over it (especially mine) so I look in the already-optimally-positioned mirror on the outside of the door where my hand goes to check if there is some other vehicle coming first before I open the door.

And I am not even Dutch.
