The Official Rules of Drinking Gran Turismo

1.1 Players must select the same vehicle on any track, provided said track has grass banks or gravel traps.

1.2 Drinks must be able to be consumed through a straw to completion, while Gameplay is taking place. Sellotaption, or sticky-back-plasticisation, of several straws together must occur if necessary.

1.3 During Gameplay, players must drink continuously while they are applying brakes, or are veering off the designated track.

1.4 The game may not be paused for any reason. If a player's drink is depleted, he/she must restock while the game continues. He/she may not accelerate during this period.

1.5 The winner has to be presented with the winner's trophy, which is a shot (ideally in a miniature trophy), concocted by the losing player, of any combination of alcoholic beverages, and edible solids.
