Every Sectional Map has big two digit numbers in each grid square that denotes the safety height for that grid.....when was the last time the average pilot looked at them while in during a pre-takeoff brief....much less in flight at night?
Anything that sets off "Martha" in your ear is an improvement even if she sometimes gives spurious warnings.
Famous last words of a pilot in South America heard on the CVR tape following an altitude alert was "Shut Up Bitch!".....quickly followed by sounds of impact that killed all aboard the flight.
