The Rules

Finally, the most comprehensive and authoritative set of Shotgun Rules I have yet come across. These rules take into account important considerations such as:
--You must be outside to call shotgun
--The car must be in sight to call shotgun (for instances when the preceding activity took place outside)
--When one party's hand is on shotgun door, other parties cannot claim shotgun
--The invalidation of Shotgun rules for long road trips in favor of rotational shotgun

It also includes the all-important Significant Others Clause in which any girl/boyfriend gets automatic shotgun privileges (violate this rule at your own peril. Ask Seth about the forces of fate that flung a side mirror at the bridge of his nose after his flagrant flouting of this principle.)
