The person taking the front seat in a car other than the driver.. originally comes from the earlier days when trams were in use and people used to get robbed by thugs during their journey.. So there was a person sitting near the driver with a shotgun to keep the thugs away.. And hence the person sitting near the driver in the front is called a shotgun..
