I don't know how or why this is always attributed to the Dutch. I'm Dutch. We definitely did not learn this. Not in school, not from parents, not in driver's ed. We do not open our doors this way.

The thing is that all Dutch drivers are also cyclists, that helps a lot. Also, our infrastructure is very very very VERY accommodating to cyclists. Often bicycle paths are separated from roads,which helps a lot.

When opening doors, we simply look. There's a mirror very conveniently placed for the sole purpose of looking behind you. Use it. If you open your doors without looking and thinking, you're an idiot. None of that has to do with being Dutch.
