Someone already posted it but it bears repeating:
The people in the pictures are NOT queuing. I can't speak for all Scandinavians but Danes generally hate standing in line. We will when necessary but there is no cause to do so until we see the bus approaching. Only then will we form a line whick looks just like in other countries. Until then people just spread out in the area by the bus stop. If it's a long bus where every door is both exit and entrance, then the line looks like the extreme photo with people several metres apart.
The gif with the girl in red is NOT a personal space reaction. Look at their heads. They've spotted the bus on the horizon and are slowly moving to their queue positions.
Also the part about never taking a seat next to someone in the bus if free double seats are available is completely true. The only people who disregard this unspoken rule are old, lonely people, junkies and drunkards.
Went out to dinner with a friend recently. Through a neighborhood with lots of restaurants. Most of them were full or almost full. We could have gotten a table. In the end we found a restaurant that was nearly empty. Only three others apart from us. Two of them in a separate room. We had all the space in the world and silence apart from the subdued background jazz. It was bliss. Food was luckily great. Came back from Tokyo a month ago. People there regularly queue infront of restaurants. That would never happen in Denmark. No available tables? We leave and find another restaurant.
Temperatures: from around 18 degrees celsius it's t-shirt, shorts and sandals.
