Overtaken after Chequered Flag

Hey i was watching my race and being very worried because i would finish with less than a litre of fuel and then i had passed the flag but after i had finished i ran out of fuel and was overtaken eventhough i had finished. Is this a bug or is it just some programing.

Are you sure it was the finish line you're looking at and not the DRS activation line? Your car should disappear as soon as it finishes. Can't see how it can run out AFTER you finished.

Actually when you run out of fuel, the car stops immediately, then disppears after a short amount of time, just like every other failure on the car that forces retirement.  In theory the car becomes a ghost before it disappears off the screen/track.
