>Most cars give you significant warnings that you're about to run out of gas and as a result very few people do.

You will see accident reports where the problem is that the pilot just completely failed to put enough fuel in the airplane and then flew it until it ran out; but that's not the typical thing.

What's much more common is that the pilot takes off with what seems like ample fuel, gets halfway there, discovers weather that is worse than expected, has to fly lower than planned, burns a lot more fuel as a result, discovers that they will have to refuel, can't find an airport with good weather at which to land, and ends up flying a graveyard spiral into a fatal crash caused by disorientation in conditions for which they are not trained.

The majority of accidents are traceable to poor planning or decision-making once airborne; and I tend to agree with the other poster that improved avionics are not going to make a really big difference.
