We have made this problem for ourselves. Everyday we go to work we strive to give our best and occasionally slip up. Then we write a safety report about the moment and what we did next to correct it.
Thus the aviation regulators have a whole host of pilot errors in their database. They sit there and comment on how many of these rather minor reports that they get so it must of course be safer to remove the pilot for the equation.
The thing they forget is how much intervention we actually do. My jet is reliable, but regularly throws it's toys out of its pram for no good reason.... Thus we intervene rather regularly, but as they don't have ANY statistics to prove any of it, the regulator is only going to come out on one side of this...
