SOLUTION: Substitutive driving is performed by using a folding type or collapsible type bicycle. The folding type or collapsible type bicycle which has been ridden by a substitutive driver is loaded on a seat and/or in a trunk of an automobile of a client for moving to assemble the bicycle at the time of reaching a destination for riding to return to the stating point. Thereby, two personnel that had been required for usual substitutive driving can be reduced to one.
