Cessna 172 Skyhawk (without G1000): Incorrect fuel indicator reading?

As an aside, in real-world no pilot would ever operate in this bingo-fuel scenario. My personal minima is to land if i’m indicating 15-20% fuel on board, as there are dregs in the tank that are unusable (AFM weight/balance should have an account for this). Then I would expect a slap from the FAA as to why I was operating in the national airspace with fuel insufficient for the flight. Under instrument flight rules, I might be running afoul of requirements for diversion and IFR reserves.

Yes it does correspond with reality. I am an instrument rated pilot and an aerospace engineer who formerly worked on several of the airplanes that are included in MSFS.

But, FS is not real world and gives us the opportunity to play with or experience things we are unable to do in real world. It is realistic to be playing a guessing game as to when you will actually experience fuel starvation.
