Accident and infringement rates are indeed the fault of the pilot when they can't navigate.
Everyone accepts that pilots using GPS will reduce the incident rate.
However, there are lots of pilots these days who like for example IO540 are constantly telling us that unless they have GPS information available they would be unable to navigate visually.
Perhaps we should thank these pilots for using GPS and recognising their failings and doing something that will reduce the carnage they leave in their wake.
But that should not be a reason for ignoring the fact that there are more and more pilots who can not navigate visually.
