When your in Puget Sound and you have to cross one of the many shipping lanes and your boat cruises at 8 knots you do care whats at 3 or 6 miles, or more to avoid be run over and to better time your crossing. It's good to know if a large ship is coming at you or going away.
But I agree that 90% of my time is spent in the 1 to 3 mile range.
