If the result that experience with L2 seems to improve situational awareness is robust, then that raises the question of why that is so. Has experience taught them that they need to pay attention, in a way that is more effective than merely being told they need to? Are drivers new to L2 overconfident in its abilities, or perhaps merely unsettled by the unfamiliarity of the situation? Note that the article also mentions that other studies have found increasing complacency with experience. > Does it make them more likely to note and deal with unexpected risks or not? The article guesses the answer though the actual paper may not have. Given that noticing a problem is a prerequisite of dealing with it, this is not an unreasonable supposition, though one should also wonder if their reaction times are slower. Note that even if that is so, noticing more things, or noticing them sooner, could more than compensate for this.
