"My issue with GPS is simply that pilots get suckered into following numbers/needles on a box in the cockpit rather than setting the aircraft up in the right direction and flying towards the landmark on the nose. IFR pilots follow needles on dials, VFR pilots follow their nose. IFR pilots follow rules that ensure they don't fly into someone else or the ground, VFR pilots use their eyes to make sure they remain safe."
I agree with Droopy.
And I never mentioned sailing with GPS! My (lost) point was that the then new 'safety toy', radar, aided the commission of several accidents through distraction and sense of security.
