   The accelerations of the free-falling elevator towards the center of   
   the   
   Earth and of the center of the Earth towards the free-falling elevator   
   are not ambiguous, because they are observable and measurable in all   
   references.

   The acceleration of the object in the elevator is really (obviously)   
   null as all the accelerations with respect to themselves are null but   
   what does it have to do with gravity?   
      
   The acceleration of gravity of the object in the elevator is directed   
   towards the center of the Earth and not towards the elevator!
