Am prompted to ask since I keep having encounters with drivers like these at this particular spot . Here are 2 different drivers doing the same thing, one view from front and one from rear camera - had another similar encounter yesterday but it happened that my camera was not plugged in.

Note that the left lane is for both turning and going straight. Is there some sort of "understanding" that I must only take lane 1 on the slip road, even if the other lane is clear ? These drivers seem to expect cars in the left lane to use only lane 1 on the slip road and leave lane 2 for them, even though at one point they are actually cutting across the path of cars who might be going straight. Or is this just plain old queue jumping ?
