GTA V offers such a huge world with so much freedom, it's not too difficult to come up with your own games in the game. Some people challenge themselves to launch themselves into cargo planes, and others try (REPEATEDLY) to drive over a bridge's support beams on a motorcycle, despite it being so difficult that most people would be frustrated by, say, the 500th failure.
But not this guy. This guy won't stop until he goes ALL. THE. WAY.
