I am after the name of a movie i saw awhile ago. From what i remember there was a nuclear war of some sort and everybody is dieing of radiation. Everyone was given medication to give them a quick death as well. I think a trip in a submarine was also involved at some point. At the end some dude decides to go out in style and races a ferrari (i think) around an australian race track before crashing in a fiery ball. Someone must know from my excellent description
