You see, there is a system. Starting from the right: pedestrians, bikes and lastly cars. We never deviate from that system, that way everyone always know where everything is. Sometimes there's a bike lane, but that still goes between the pedestrians and the cars.
Also, if everything else fail, and this is what kids in Denmark is taught. If you're ever in doubt if the drivers have seen you, assume they haven't and stay away from the cars. You're on a bike, it's a great means of transportation and it's really safe (at least here), but if you're hit by a car, it's going to hurt you more than the car, so stay away from them.
I think it's weird that people in countries that have the most cyclist are also the people who least of all believe that bikes have some weird right of way or than bikes should just be in the middle of heavy traffic.
Conversely, it makes sense that a country with chronic bike infrastructure baked into the legal system would assume bikes use that infrastructure. If there is a safe, protected bike lane, I’m happy to use it.
In other countries, bike infrastructure is sparse, poorly designed, and frequently dangerous. Bicyclists must drive defensively to stay alive. Sometimes this means taking the full lane because staying to the side puts you in danger of dooring or makes you vulnerable to aggressive drivers who will squeeze by without adequate space.
The point is, that they aren't suppose to be in the middle of road.
