“For decades now in the Netherlands drivers have been trained (and tested for their licenses) on a behavior that dramatically reduces the risk of doorings. They do not even have a name for it because it is simply how one opens a car door. Basically, instead of using their door-side (left) arm, they reach over with their other (right) arm. This simple behavioral shift causes drivers to look back naturally and see whether or not there are oncoming bicyclists.”
