Yeah, I think it's quite common in most places for the same reasons you mention. And a human or an autonomous car with more situational awareness can deal with those situations by being extra alert and careful and keeping a pre-planned problem resolution at hand (ie, ensuring there's space behind/at the side to emergency break while passing).
But the Tesla just drives right into it, keeps a speed that might as well have been planned to make it invisible to the truck, while closing the distance to the car in front in a place where the road layout makes it look like it's intentionally cutting people from the merging road off from being able to take the exit. It's really bad behaviour.
I can't even say that it's good that it's collision avoidance managed to avoid the collision, because it that's how it works, there's a high chance that people will start to figure 'oh, look, I'm being cut off by a Tesla being a dick. No problem, it's fast enough to deal with me forcing myself into its lane.'.
