On the other side of the equation in is reasonably easy for a gps operator
to maintain someting close to optimal clearance of hard stuff. It is a
complex and difficult task for a pilotage operator to do the same.

LOL Only part I think needs clarification.
In coastal navigation (especially on much of the US West Coast), if the
operator knows what he/she is doing, it is neither a complex or
difficult task to maintain optimal clearance of hard stuff, under normal
"piloting" conditions.
