If you’re about to run out of gas in a car it’s usually not a big deal - you find the nearest gas station and go there. Usually. There are exceptions like driving 100 miles of desert with no gas stations in sight and forgetting to put enough gas in. If that was the common driving scenario I’d bet way more people would run out of gas, and no warning light will help.

Flying a plane is often sort of like that - planning mistakes tend to become problems with large time windows where a warning light is way too late to affect the outcome. Flying into a long narrow canyon is another example where your fate can be sealed minutes before you actually fly into the mountain.

All of this can and should be made better with technology, but a lot of flying hazards are more complex than “warn the user about something happening in the next few seconds”.
