One of the big things that concerns me about the X in the event of a fire or an accident that disables the falcon doors (say, 12V system failure due to serious front impact damage) how do you exit? According to the First Responder's guide, the method if power is lost is to remove the speaker grills and pull the manual release cable. How would a passenger know to do this? It's worse if a fire is involved. I don't like that. At least on the S the door release cable is easy to pull without the speaker grill.
Also, I'm wondering if the doors automatically unlatch in the case of an accident (I would guess they do, but I don't see anything in the guide that says they do.)
