JB,  Did you happen to notice this 'gem' of a ruling from the US Federal Aviation Administration : 
Foreign pilots may be distracted at SFO doing parallel landings
Apparently there have been a couple of 'go arounds' at SFO since the Asiana crash whilst landing in parallel with another craft, leading the FFA to say (or be quoted as saying): 
.
So, according to the FAA, 'foreign' pilots, as a group are more easily distracted than US domestic pilots, so much so it endangers the craft, hence the ruling.  Reckon there's a grain of truth in that? :shock:  
 
BTW I landed at SFO on Friday, on a United A320 exactly in parallel with a Delta bird of about the same size.   I dunno about our pilot, but I was mesmerized!
