The surrounding environment affects people to interact with an object differently. Take the simple car door. The dutch have a lot of cyclists, and most drivers frequently ride a cycle. So, it’s intuitive (to them) that a cyclist might be in your blind spot when you’re opening a door. So, using the far hand to open the door, allowing you to peek at the blind spot before opening the door, only seems natural.

This is the Dutch Reach .

Did you notice the other thing the driving instructor (in the video) said in passing? Holding the door with the left hand because it’s windy? Tells you a lot about the environment and how people interact with objects taking the environment into consideration.
