When you're hand flying down by the ground in the clouds doing stupid shit, no nanny system is going to save your ass. If it could, it could also put you in the dirt with any malfunction.
I went out on a search and rescue back in the 90s for an A-6 Growler with such a system on board, it was the latest technology. They were 500 feet up doing 500 knots and then the electronics decided to go plow some dirt for a while. It was all over before the pilots could disengage the system.
How about we talk about the fact that the pilot flew VFR into IMC, which is the #1 killer of pilots world wide. Safety mechanisms only go so far, if your pilot is determined to fly into weather that he is either not equipped to handle or not adequately trained on (not saying that is the case), then you're in for a shitty flight.
Continued VFR into IMC is the scourge of general aviation. Year after year, it is a leading cause of fatal accidents—almost four times deadlier than

So in the years since then (>20 years), no progress has been made to alert the pilot that they are about to collide with a mountain/building, in this case for helicopters
. I'm not saying it would nanny them, but a least give them a clue of where they are in relationship to their surrounding, specially where visibility is very limited. What the point of having all this instruments in front of the pilot if it doesn't warn them, even if they are IFR rated. This is an unbelievable that it can still happen with all this technological progress in avionics we've had in last 20+ years.

I've seen the loss of my Dads friends (2 pilots and 3 executives for a aircraft company) whose 2 engines aircraft plowed into a mountain in the mid. 70s, due to bad weather and limited visibility. Pilots had years of experience, both VFR and IFR. Another similar aircraft that was flying with them, pilot decided to take another route/land. Can't remember which since I was about 15 years old then. Witnesses nearby said that they heard a loud boom., in the heavy rain Joined the search party my Dad helped organized, needless to say their bodies where found in pieces and you could smell death everywhere. Their body or parts of it where in a sealed coffin. I've my own experience of near mishaps and still have nightmares about them.
