Thousands of pilots are alive because they don't make such errors. They are trained and competent in the equipment they use. Pilots who are not trained or not competent will kill themselves and their passengers no matter what equipment they carry, especially if they are lulled into a false sense of security that the equipment will do all the work for them.
I reckon in an emergency if locked above IMC to ground level and no where else to go it would very likely get you on the runway.
It will more than likely just get you to the crash site.
