Driving is an unnatural, fairly sophisticated activity that many people don't have an intuitive sense about. Especially when it comes to the proximity of danger to themselves or others.
I live in a developing SE Asian country where the only rule is: there are no rules. You can assume that everyone will always maneuver for their own benefit, especially if their vehicle is larger. This includes turning right in front of you, driving the opposite way, and stopping in the middle of all the lanes.
In a sense, this brings a certain type of order because it's predictably disordered. The key rule is that you will die if you trust anybody to look out for you except yourself.
