  Interstate exit signs are carefully chosen for clarity - using only the 
immediately-connected road in exit_to can result in a situation such Tulsa, 
OK where Skelly Drive parallels I44, and there would be many exits with an 
immediate link to Skelly Drive: 
http://www.openstreetmap.org/?lat=36.0895&lon=-95.95508&zoom=16&layers=M - 
totally confusing someone who uses that information.

  Sign relations are less ambiguous, but there is no editor assistance.  In 
many cases, a destination city on a sign will be hundreds of KM distant, 
which again complicates trying to locate the object to add to the sign 
relation.
