The Snaefell Laverda Biker Car by Francoes Knorreck
Riding shotgun refers to the practice of sitting alongside the driver in a moving vehicle. The expression was applied originally to the movie depiction of stagecoaches and wagons in the Wild West, in danger of being robbed or attacked. An employee or passenger (Mr Skull N Roses) would sit beside the driver (you!), carrying a shotgun or rifle, to provide an armed response in case of threat to the cargo (silver) or passengers (BJL Crew).
